gwen took back the sovereign next morning to netta, who received it with amazing coolness.

"an unexpected blessing," she remarked. "i'd put that sov. down as a bad debt. better late than never. we're quits now, gwen gascoyne."

"not altogether," returned gwen. "i've set my part straight, but you've still got the credit for my essay. you haven't put that to rights."

"catch me telling!" laughed netta. "no, my good gwen, that's a little too much to ask. don't expect more than you're likely to get, and then you won't be disappointed. i'm afraid i must still consider mr. thomas carlyle my special property. you really can't eat your cake and have it."

"that's exactly what you're doing," retorted gwen. "you took my essay, and now you've got the sovereign as well."

"but i helped you out of a temporary difficulty. you forget that, and don't show as much gratitude as you might."

"not much cause for gratitude," grunted gwen.

"this is what comes of being too philanthropic. i won't help anybody out of scrapes again. one never gets thanked for it."

[251]

"not when you give your help on such terms."

it was no use arguing with netta, so gwen turned away, glad to have closed the transaction, even though she had been decidedly the loser. there were plenty of other matters to occupy her mind, as this afternoon the tennis trials were to take place as a preliminary to playing for the form trophy, and later for the county shield. gwen had given in her name to moira thompson, the head of the games committee, and expected that she would be accepted at least for the trials. nor was she mistaken, for when, at two o'clock, moira pinned her paper on the notice board, the fourth couple down for singles were gwen gascoyne against geraldine french. all the school was assembled to watch the play, since on this afternoon's victories would largely depend the future choice of champions.

"here's my new racket. do use it—it's a perfect beauty," whispered lesbia, edging through the crowd, and pushing her treasured possession into her sister's hand. "it will just make all the difference to your play."

gwen accepted the loan thankfully. her old racket had been her greatest impediment, and she had not liked to borrow often from her classmates. as lesbia had prophesied, it made all the difference to her serves, and she played up in a way that astonished everybody. geraldine french, who was considered almost invincible by the sixth, had not taken gwen seriously, and was therefore most electrified and disgusted to find herself beaten by a fifth form girl of no particular reputation in the world of tennis. the fifth were in a state of immense delight.

[252]

"gwen's serves to-day were unique," declared iris watson. "if she can keep this up our form may have a chance for the trophy."

"i'd no idea gwen could do so well," agreed elspeth frazer. "she's suddenly developed into quite a crack player."

"and she's such long legs and arms, she seems all over the court, and scarcely misses a ball."

"she's shown up in a new light this afternoon. we shall have to think her over for a championship."

the match for the form trophy was to be played in a week's time. at present the beautiful silver cup was in the possession of the sixth, but the fifth were not without hopes of winning it, and transferring it to the chimney piece of their own classroom. it was an old-established custom at rodenhurst that after the trials had taken place each form competing for the trophy should vote its own champions. the election was naturally a highly exciting event; all the points of the various candidates' play were carefully discussed, and the two who were considered the most likely to do credit to the form were returned. on this occasion five girls appeared of such equal merit that the running between them would be very close. hilda browne and charlotte perry were last year's champions, and were steady players, though many thought that charlotte had gone off a little in her serves. betty brierley was brilliant but unreliable, sometimes making more splendid scores than anybody in the school, and sometimes playing love games. netta goodwin had a special reputation for back work, in which she excelled, and this circum

[253]

stance might very possibly cause her to be chosen in conjunction with a good net champion. gwen's unexpected prowess had been a complete surprise to the form, and had made such a favourable impression that many were inclined to vote for her. to none of the five girls did the vision of a championship appear more attractive than to netta. she loved to shine, and it was a sore point with her that she was not more popular in her form. here, at any rate, seemed a chance to gain the applause of her schoolfellows. she was conscious of playing well, and though she was not a general favourite, she knew the girls did not allow individual preferences, as a rule, to bias their judgment when it was a question of winning or losing the trophy. she canvassed diligently, put any pressure she could bring to bear upon her particular friends, and began carefully to reckon up how many votes she could reasonably count upon. the result was not altogether reassuring. both hilda browne and gwen seemed powerful rivals to her pretensions, and the chances were that the election would return hilda for first champion, and either gwen or charlotte perry for second. the prospect of being beaten in an affair upon which she had set her heart filled netta with dismay.

the voting was by ballot, and took place in the classroom immediately after morning school. when the bell rang the girls did not immediately leave their desks as usual, but sat still while miss douglas distributed to each a half sheet of notepaper and an envelope. all that was required was to write down the names of two champions, fold the paper and put

[254]

it in the envelope. no signatures were allowed, so that even miss roscoe should not know who had voted for which candidate. the whole affair did not take more than a few minutes. the girls hastily scribbled the names of their favourites, many of them in feigned handwritings, fastened their envelopes, and then returning them to miss douglas, left the classroom.

"i wonder how soon we shall know the result!" said netta, as the form trooped downstairs.

"it depends upon how soon miss roscoe has time to count them," replied iris watson. "she may be in her study now, or she may be too busy to look at them until four o'clock."

"too bad to leave us in suspense."

"i'm not going to think about it," said charlotte perry. "it will be time enough to rejoice or moan when one knows."

"oh, bother the election!" said betty brierley. "come and see if we can get a court and have a set before dinner."

netta did not follow the others to the tennis grounds. she was much more anxious about the result of the ballot than they, and had no heart at present for playing. instead, she walked into school again, and finding the door of miss roscoe's study open, she peeped in. the room was empty, and on the desk lay the nineteen envelopes, each marked solely with a large v, that represented the voting of the fifth form. netta looked at them wistfully. how she longed to open them and learn their contents! such a proceeding was, of course, impossible,

[255]

and she turned away with a sigh. as her glance wandered round the room, she noticed a large parcel of stationery which had just been unpacked, and lay spread upon a side table. miss roscoe had evidently opened it to get the paper and envelopes needed for the election, and had not yet had time to put it away in the drawers of her secretaire. then suddenly an idea occurred to netta—an idea so original and daring that she almost laughed at her audacity in entertaining it. it was a scheme which no other girl in the form would have dreamt of for a moment, but netta was troubled with few scruples of conscience, and was never deterred by a question of honour from attaining her wishes. very quickly she abstracted nineteen envelopes and ten sheets of notepaper, and fled with her spoil to her own classroom. she bolted along the passage and upstairs in such a tremendous hurry that she did not notice the impish face of ida bridge peering from the second form room as she passed.

"oho, miss netta goodwin! what's the matter with you?" thought ida. "you have an uncommonly guilty look about you, almost as if you were committing a crime. what's up, i wonder? i think i'm just going to track you and see."

since the stormy episode on the day when the second form girls were rehearsing for their morris dance, ida bridge had detested netta. she felt she owed her a grudge, which she was most anxious to pay if a reasonable opportunity could only be found. she followed now post haste, and adopting the tactics of a scout, waited till netta was safely inside the

[256]

fifth form room, then peeped cautiously round the door. what she saw did not particularly enlighten her. netta was busily tearing sheets of notepaper in half, was scribbling something on them, blotting them and putting them into envelopes. no one else was in the room, and there was nothing to suggest an explanation of this rather mysterious employment.

"i'm sure she's up to something, though," murmured ida to herself, still keeping a watchful eye on the enemy's movements. netta wrote away, and kept folding her pieces of paper with record speed; there was a complacent look on her face, and she chuckled occasionally, as if with deep satisfaction. at the sound of the dinner bell she started, and hurriedly swept her correspondence into her desk. ida, with admirable presence of mind, bolted into the empty sixth form room opposite, and having seen netta depart down the corridor, took the liberty of going to make an inspection of what she had been doing.

"um—indeed! what have we here?" said ida, opening the desk. "envelopes marked with a v, and sheets of paper with names on. let's take a look at them. 'hilda browne—netta goodwin.' 'netta goodwin—gwen gascoyne.' 'betty brierley—netta goodwin.' 'charlotte perry—netta goodwin.' all in such different styles of writing, too! i believe i begin to see daylight. now, shall i go and call miss douglas at once to look at this? no—it's incriminating, but not sufficient evidence to convict. i must let things develop a little further first. i think i'd better have a witness, too. miss netta goodwin, i believe you're going to be rather too

[257]

clever for once, and that you'll find yourself outwitted by one of the despised juniors."

ida bridge was late for dinner that day, but she took miss roscoe's reproof with a sangfroid at which her form marvelled.

"i don't care if i have to write fifty lines as a punishment," she murmured to her neighbour and chum, peggy weston. "what i've just discovered is worth a thousand lines. i can't explain why now, but the moment dinner is over you and i must stalk netta goodwin, and, without letting her know it, never take our eyes off her till afternoon school begins."

quite unconscious that two small spies had resolved to keep her movements under surveillance, netta slipped away from her friends after dinner, and returned to the classroom. it did not take her long to finish her task; she had soon fastened her nineteen envelopes, then, concealing them in an exercise-book cover, she hurried downstairs. miss roscoe's study was still empty, and nobody seemed about, for netta never noticed the cautious pair who were dodging and watching in her rear as cleverly as a couple of young detectives. after a hasty glance round the room she advanced to the principal's desk, and deeming herself quite unobserved, rapidly exchanged the pile of envelopes there for those which she had brought with her. she gave one look of satisfaction at the substituted set—they were such an excellent imitation—and bore off the genuine ballot to the fifth form room. ida and peggie, with breathless interest, followed, and saw her putting the stolen

[258]

goods into her desk; then, having witnessed as much as they considered necessary, they flew in hot haste to lodge the information with their own form mistress. miss broughton, amazed at what they told her, sought miss roscoe, who summoned ida and peggie, and listened attentively to their story.

"this must be enquired into promptly," she declared. "come with me at once to the fifth form."

the girls had just assembled for afternoon school when the principal entered, bearing the substituted pile of envelopes, and accompanied by ida and peggie.

for miss roscoe to arrive at such a time was an absolutely unprecedented occurrence. a dead silence at once reigned. everybody wondered what had happened, and why miss roscoe should have brought the two children with her. the headmistress walked straight up to netta's seat.

"netta goodwin," she said, "such an extraordinary incident has just been reported to me that i feel it is my duty to investigate it immediately. i wish to see what you have here," and, throwing up the lid, she began to investigate the contents of the desk.

netta gave a gasp as if an earthquake had opened at her feet, and turned deathly white. she did not venture to say a word. all in the room waited in mute suspense, realizing that the matter must be of vital importance. with a sad face miss roscoe drew out the nineteen envelopes and compared them with those which she held in her hand.

"i have a very serious charge against you, netta

[259]

goodwin," she said sternly. "you were observed in the act of taking these letters from my study, and substituting a similar set which you had yourself written. ida bridge and peggie weston can testify that they themselves witnessed your deed. i have a strong suspicion of your motive, and i am going to open the envelopes to ascertain if i am correct."

putting each pile separately, miss roscoe rapidly tore open the two ballot sets, and glanced over them.

"it is a peculiar circumstance," she remarked icily, "that in the original voting papers your name occurs only nine times, and in the substituted papers eighteen times."

a wave of indignation passed round the form. the girls at last understood the point, and realized the full significance of netta's action. the excitement was intense, though awe for the headmistress forbade anybody to speak.

"to make absolutely certain," continued miss roscoe, "we will take the voting again. miss douglas, will you kindly deal a sheet of exercise paper to each desk? now i put everyone on her honour to repeat the names of the two candidates that she wrote this morning."

for a moment the girls scribbled, then folded the papers and handed them to miss douglas, who went round the room to collect them. miss roscoe examined them attentively, and compared them with some figures she had jotted down.

"they correspond absolutely with the papers which i have just found in your desk, netta goodwin! ida

[260]

bridge, come here! it is only fair that netta should hear your accusation. tell me again, in her presence, exactly what you witnessed."

"please, miss roscoe," began ida in her high-pitched voice, "i saw netta come out of your study before dinner, and come here. i peeped round the door, and she was writing something on half-sheets of paper, and putting them inside envelopes. then i told peggie, and afterwards we watched her go into your study again and put her pile of envelopes on your table, and take yours away and pop them into her desk."

"do you endorse this statement, peggie weston?"

"yes, miss roscoe, it's quite true," murmured peggie nervously.

"netta goodwin, have you anything to answer in reply to this charge?"

but netta kept her eyes on the ground, and did not reply. miss roscoe, who was still standing beside the open desk, began to turn over some of the loose pieces of exercise paper which it contained, and shook her head as she noticed the names of various candidates scrawled in different handwritings, evidently for practice. determined to investigate the affair thoroughly, she pulled out yet more papers, and among them a small roll fastened by a brass clip. at this she glanced with attention, then with marked surprise. "netta goodwin," she continued, "this is an entirely different matter, but one which i should like explained nevertheless. last term you gained a prize for an essay on thomas carlyle. how is it that there is a manuscript of this essay in your

[261]

desk, signed 'gwen gascoyne'? yes, and in gwen's handwriting, too, which i know well."

netta glanced hastily at gwen, who had turned as red as fire. perhaps feeling that she had already been so entirely exposed that an added circumstance would make little difference, and wishing to get gwen also into trouble, netta suddenly resolved to make a full confession.

"i suppose i may as well tell everything," she volunteered sulkily. "yes—i did want to get the tennis championship, and i altered the names because i didn't think i had a chance otherwise. about that essay, it was gwen gascoyne's. she wrote it, but she sold it to me for a sovereign."

"and you passed it off as your own?"

"i'd paid for it, so i just copied it. i couldn't see where the harm came in!" said netta doggedly.

"netta goodwin, have you absolutely no sense of right and wrong, or any vestige of conscience?"

"i can't see that i'm worse than some other people," replied netta, with a spiteful glance at gwen.

"gwen gascoyne, did you sell this essay to netta?"

"yes, miss roscoe," gulped gwen, covered with shame, and too much embarrassed to offer any explanation.

"i shall have a word with you later on. netta, by your own confession you admit appropriating a schoolfellow's work last term, and altering the voting papers this afternoon. forgery is a very ugly word and one which i am sorry to use, but there is no other name for what you have done. in all the

[262]

years of my headmistress-ship here such a thing has not occurred before. i have had unruly and disobedient girls occasionally, but in the whole of my experience never a girl so deliberately bad as you. it is well for the school that this has occurred, and that i have discovered your true character; your influence must have been most pernicious, and i can only hope that it has not already done harm. it is, of course, impossible for me to allow you to remain at rodenhurst. it is the first time i have been obliged to expel a pupil, and i much regret the necessity, but i feel that to keep you would be to retain a source of moral infection. you will go home at once. your books and any other articles belonging to you will be sent after you, and i shall write to your parents, informing them of the circumstances under which you have been sent away. i am grieved for the sorrow which i know it will cause them. go!"

miss roscoe pointed peremptorily to the door, and netta, all her jaunty, self-confident airs gone for once, with downcast eyes that did not dare to meet the scorn of her schoolfellows, and white lips that quivered with passion, slunk ignominiously from the room. the principal waited a few minutes to allow her time to go downstairs, then she ordered ida and peggie back to their own classroom, and turned with a sigh to gwen.

"you will come with me to the study," she said briefly. gwen followed in a state of abject misery. was she never to finish reaping that harvest of tares, the sowing of which she had already so bitterly re

[263]

pented. one initial slip had indeed plunged her into undreamt-of trouble.

"well, gwen, you had better tell me all about this unhappy business," said miss roscoe as soon as they were alone. "let us get to the bottom of everything this time, and leave nothing concealed."

hard though it was to make confession, gwen was almost glad to have the opportunity of doing so, and of at last setting straight the last threads of the tangled web she had woven. she felt that she would have told before about the essay if netta had not been implicated, but her father had agreed that she could not in honour expose her schoolfellow. by skilful cross-questioning miss roscoe soon gathered the facts of the case.

"i understand," she said thoughtfully; "i am glad you paid back that sovereign, gwen! it gives me a higher opinion of you than i should otherwise have had. i judge that your own conscience and your father's disapproval have punished you so severely that i can add little more in the way of reproof. i can trust you not to do such a thing again. do i now know absolutely the whole of that transaction?"

"every scrap!"

"then we will consider the slate wiped clean."

"thank you just a thousand times!" said gwen, as miss roscoe with a nod dismissed her from the study.
