three days of waiting was the utmost i could force myself to endure. on the afternoon of the fourth i called at the house on the side street. the door was opened by the irishwoman, who met me with a broad grin.

"oi looked for ye sooner, sor!" was her greeting.

"señorita vallois—?"

"flown, sor,—more's th' pity! ye're a loikely lad, sor, if ye'll oxcuse th' liberty."

"gone?" i muttered. "her uncle—?"

"came an' packed her off, bag an' baggage, two days gone."

"two days!—where?"

"'tis yersilf, sor, is to foind out th' same," she chuckled.

i held out a piece of silver. "will that jog your memory, mistress?"

"divil take ye!" she cried, and she struck the quarter dollar from my hand. "am oi a black traitor to sell a fellay christian to a heretic?"

after that there was nothing to do but turn on my heel and leave the virago. by one false move i had lost her friendship beyond recall.

for weeks i sought to trace the señorita and her uncle. all i could discover was that the don had come from philadelphia in his private coach, called at the british legation, and carried away his niece by a route unknown.

left with no more than that doubtful mention of new orleans, i plunged back into the social swim of the federal city; not to forget her,—that i could not have done had i wished,—but to wear away the months of waiting and to perfect myself in the social graces so far as lay within my capacity.

at the same time i did not forget to press my application with secretary dearborn and other members of the government, who, i found, were all too ready to forget me. it was a hopeless quest, and i was well assured of the fact before midwinter. yet it served its part as a time-killer; and the season being too far advanced for the descent of the ohio by boat, it was far more agreeable as well as advantageous for me to while away my enforced holiday in washington than needlessly to punish myself by the long and wearisome horseback journey to the mississippi.

so i lingered on, dancing attendance on officials who frowned, and dancing the minuet with ladies who smiled. each served its purpose in carrying me over what would otherwise have been a most tedious winter.

march came and dragged along more than the due number of weeks of foul weather. yet with the approach of the vernal equinox i began to overhaul my buckskins. being well able to imagine the state of the roads, i had started a chest with the bulk of my wardrobe by wagon to pittsburg ten days in advance, and all my preparations had been made to follow after, when the post from philadelphia brought me a letter which caused me to change my plans in a twinkling. i should rather have termed the missive a note. it was without date, and ran thus:

"if dr. robinson is interested in learning of a project contemplated by two parties whom he met at dinner,—to wit, a certain foreign gentleman and the writer,—he will, on his return west, come by way of philadelphia, and call upon the writer.

a. b."

much as this language smacked of intrigue, i had no hesitancy in changing my route to comply with the note. it was not that i felt any interest in the projects of colonel burr or his associates. the point was that to my mind "foreign gentleman" spelled "señor," and i had met but one señor at dinner in the company of aaron burr. if señor, why not señorita? the rest follows as a matter of course.

my faithful nag had not gone unridden through the winter. a man does not always give over the habit of a daily outing because of balls and routs and tea-sippings. yet the roads north might have been better—which is not saying much,—and there are limits to the endurance of a beast, though not to the miriness of a seaboard road in the spring rains. i did not make the trip to philadelphia in record time.

upon my arrival i found that even the beast's master would be the better for a night's rest. directed to the plow tavern, i demanded food and drink for man and horse, and having washed and supped, soon found myself pressing the clean linen of my quaker host.

business justifies calls at early hours, and i did not breakfast late. it was as well, perhaps, that i missed my way in the square-laid but narrow quaker streets, and did not find myself upon the doorstep of colonel burr until midmorning. even as it was, i had a wait of several minutes in the drawing-room before the colonel entered, wigless, unshaven, and loosely attired in nightgown and slippers.

while waiting, a casual survey of the room had surprised me with its evidences of a lavish establishment. gossip had reported that the colonel was not meeting all his extensive indebtednesses when due.

he greeted me with bland cordiality, notwithstanding the inapt hour of my call.

"welcome, doctor, welcome!" he exclaimed. "better late than never, eh?"

"you are kind," i replied. "i fancied that i had come too early."

he glanced at his dress with a shrug. "wine and late hours carry through many a successful conference. you will join me in a cup of coffee and a roll?"

though i had no wish for food, i assented, for i saw that he had not yet breakfasted. we were soon seated in a snug little den of a room, sipping as good coffee as i had ever tasted at any other than a creole table.

few men whom i have met have greater command of their features than has colonel burr. on the other hand, few are as over-sanguine. he must have inferred that my speedy response to his note meant outright eagerness to share in the projects at which he had hinted. scarcely pausing for a few civil inquiries as to mutual acquaintances in the federal city, he interrupted my answers in the midst.

"let that wait, let it wait, doctor!" he exclaimed, with an ingratiating smile. "there is something of greater moment to us both. i take it from this personal response to my note that you are not uninterested in the plans of señor vallois and myself."

the mention of the señor's name drew from me a sharp nod of assent. the plans of señor vallois could not but concern his niece, and consequently myself. the colonel nodded back, and his smile deepened.

"you are aware," he began, "that i have contemplated the purchase of a large tract of land beyond the mississippi, within the spanish boundary, on a tributary of the red river."

"the project was mentioned by you at the president's house," i replied.

"but the ulterior purpose of the scheme—"

"it is reported that you have planned for a colony."

"as a move necessary to the advancement of the real project," he explained.

my look of interest was not assumed. for months past many hundreds of persons, enemies no less than well-wishers of the astute colonel, had been guessing at the real object behind his rumored schemes.

he nodded shrewdly, and went on, almost in the words of senator adair: "have you considered, doctor, the fortune in store for whoever opens an overland trade with santa fe?"

"granted, sir. no less have i considered the improbability of obtaining such trade concessions from the spanish authorities. it is only too well known that their policy is set upon jealous exclusion. their desire for contact with our western borderers is as slight as their racial and religious aversions are deep-seated and abiding."

"say rather, their political aversion. better still, say the political aversion of the authorities alone. i have reason to believe that the people of mexico would welcome closer relations with us."

"it is not possible!" i protested.

"have you never thought that the spanish colonies may be as desirous of achieving independence from foreign oppression as were our own?"

"there is the contemplated expedition of miranda to caracas to speak for that," i assented.

"we have the outcry of our insolent friend the marquis of casa yrujo to testify as to the spanish view of miranda. the point is, if an expedition to south america, why not one to mexico?"

"a conquest?" i inquired—"an extension of the vast westward boundaries of louisiana territory? it is true that war with spain now seems inevitable. there is no doubt that the government would proceed to hostilities, were it not that the french minister intimates that the emperor will not permit the war."

he gave me a cunning look. "ay! with a napoleon behind him, general torreau has no difficulty in intimidating our meek philosopher of the white house. yet the emperor is powerless. england's fleets guard the high seas. the time is ripe to strike at spain. we shall precipitate the war, and to us shall fall the prize! let our object remain unnamed. enough that señor vallois speaks for certain fellow haciendados of wealth and influence living in the northern part of new spain, that portion of the country above the territory of the viceroyalty and under the government of general salcedo."

"whom they term the governor-general of the internal provinces?"

the colonel nodded. "these friends of señor vallois are far from content with present conditions. they would gladly throw off the yoke of spain if the occasion presented itself. my plan is to present the occasion by means of an army of invasion, to be allied with the revolutionary party. there are thousands of adventurous riflemen west of the alleghanies not unready to follow an able leader to the land of the montezumas."

"i have lived on the frontier too long, sir, to doubt that the tide of our westward emigration will roll on until it breaks on the vast desert of the western plains."

"i care not for the tide, sir! we shall set in motion a wave that will roll across the desert into the golden paradise of el dorado!"

"and you would tell me a man of señor vallois's intelligence invites the entrance of that wave?"

again the colonel gave me a knowing smile. "it will be for the mexicans to care for their own interests when the time comes. men do not traverse deserts and destroy governments without thought of reward. my fiery friend general jackson of tennessee is champing with eagerness to share in the conquest of the spaniard. would he be so eager were it explained to him that the object of the invasion went no further than the freeing of the people of that remote land? but there will be glory and recompense for all, and to spare. i have pledged señor vallois that he and his friends shall gain a free government, and with it security for their estates. it is his own concern if he and they misconstrue the statement too much in their own favor. on the other hand, jackson is a man far hungrier for glory than for gold. he will lead our victorious army south into the viceroyalty, to capture the city of mexico, while we are shaping the new government for the whole."

the magnitude of the scheme struck me dumb. the colonel noted the fact with satisfaction. he tapped the table significantly. "that government, doctor, is already in process of formation. as originator and leader of the project, i claim the supreme office. certain other of the higher offices are allotted. but you, sir, are a man of scientific attainments and proven courage, and, what is no less important in a royal court, you are a gentleman."

"royal court?" i muttered, wondering what more might follow.

"the spanish-american is not qualified to enjoy a republican form of government. upon this señor vallois and myself are clearly agreed. the plan is a constitutional monarchy or empire, with a restricted franchise, the voters to be confined to the ranks of the wealthy and the intellectual."

"in neither of which classes will be found the bulk of your invading army. i foresee a revolution to cap your conquest," was my comment.

"men can be managed," he replied. "there will not be lacking the spoils of office and the plunder of the enemy to lull their discontent. with all their leaders bound to us by self-interest, it will not be difficult to hold the mass in check. señor vallois guarantees a stout auxiliary force of native militia."

"with whom our rough frontiersmen will make short work, in sport, if not in deadly earnest."

"perhaps,—if brought in contact while not under the fire of the common enemy. pray do not imagine me so dull, sir. the point has been foreseen, and has been discussed with men of military training. the army of invasion will remain the army of invasion. west of nuevo mexico is the remote pacific province of the californias; south of the city of mexico—"

"you think to conquer an empire!" i cried, overwhelmed.

"why not?" he returned, with an assurance which for the time swept me off my feet in the current of his flashing dreams.

but this giddiness was not alone due to his bare statement. behind the daring words i had seen what to me was the lure of lures. i had been offered in substance, if not in words, an office of dignity in the court of this future royal personage, among whose lieutenants was numbered the kinsman of señorita vallois.

what wonder if for the moment i forgot the worth of republican citizenship in the glittering dream of titled office? what wonder if in the intoxication of the moment i saw the barrier flung down between myself and her, and thought to barter my birthright as an american for a vassal estate which should bring me within reach of her?

"an empire!" i repeated. "the spoils to the victor—and to his followers. at what, sir, do you appraise my worth?"

his answer was ready to glibness: "the title of marquis, an estate to support the dignity, and a seat in my privy council, or such other office as your merits may indicate during the consummation of our projects."

"you have made sure of señor vallois?" i demanded.

"he is with us hand and glove. i have planned to cross the alleghanies about midsummer. señor vallois has gone before, to negotiate with certain persons at st. louis and new orleans, whom otherwise i might find difficult of approach."

"he has gone west?" i repeated, unable to credit my ears.

"at my request. it was required that he should go by way of new orleans, in any event, and the coastwise voyage is far from pleasant at this season. hatteras has an evil name in equinoctial weather. also there is danger of spanish pirates off cuba and in the gulf. it is hard to find passage in other than an american ship, and a cannon-ball or musket shot fired by a spanish pirate at a yankee hull would not turn aside to avoid the spanish don who chanced to be aboard that selfsame yankee."

masking my eagerness with a smile at the conceit he pictured, i remarked in as casual a tone as i could command: "the don, then, is well on his way to st. louis?"

"not he!" snapped the colonel. "it is now only seven—no, eight days since he started. knowing the condition of the roads, i advised that he should take to the saddle, and leave his charming niece to continue her visit with my daughter theodosia, who, as doubtless you have heard, is the wife of senator allston of south carolina. i may mention in confidence that my son-in-law is one of the foremost of all those interested in our grand project. when i begin my second western tour, both he and my beloved theodosia and my little grandson will accompany me."

"from all that i have heard, sir, mrs. allston has only to make an acquaintance to find a friend," i said.

his fond ear was quick to catch the sincerity of my tone, and a look of the most profound and unselfish love ennobled his crafty face. but my own love cried out for an ending of the bitter-sweet suspense.

"so señor vallois was so ill advised as to take with him his niece?—or was she not his daughter?" i commented.

"his niece. did you not meet her at the table of our jacobin philosopher? to be sure you did! i have not so soon forgotten that gallant exploit with the fence rails!... thanks to the obstinacy of her uncle, she will be muddying that dainty arched foot in the wayside bog for days to come. there will be few dr. robinsons between here and pittsburg to pry out the carriage of the bemired dulcinea."

"ah, well," i observed, "doubtless the señor will arrive in time enough to take advantage of the spring fresh. what he loses on the road he will regain by the added swiftness of the ohio's current."

"true—true."

"i had myself thought to take advantage of the early floods. my interests impel me to return to louisiana as speedily as possible."

the colonel gave me another of his shrewd looks. "you will not take it amiss, doctor," he said, "if i repeat current gossip that the object of your winter in the federal city was not attained." i nodded, without show of offence, and he added quickly, "as well, as well, my dear sir! it has brought you better fortune, and your wish atop! you shall have a letter from me to general wilkinson."

the suddenness of this took me unawares, but he had turned at the words to summon the servant, and did not observe my confusion. calling for pen, ink, and paper, he turned again to me with outstretched hand.

"your hand to it, doctor!" he cried. "you are with us?—you cast in your fortune with the future empire of the west?"

"a word, sir," i protested. "the heritage left me by my father was scant as to property, but i have found it rich in wisdom. it included this old adage, 'look before you leap.'"

"good! good, sir! most excellent advice! yet have i not shown you the prospect?"

"you have, sir, and not without avail. it is an alluring prospect. i confess myself tempted. yet—i have seen what the french term the mirage. i should prefer to hold my decision until i have dipped my cup in the lake and found it filled."

"eh! eh!" he chuckled. "i'll wager there's scotch blood in your veins—scotch blood!"

"at the least, i would look closer at the water," i insisted.

"you shall, sir—my word for it!" he responded, with an assurance which shook my last doubt. "you shall have the letter to wilkinson. when it has brought you your wish, then, and not until then, need you consider your pledge binding."

"sir," i said, tempted beyond my strength, "i accept the terms."

"your hand to it!" he cried, and his soft white fingers closed about mine with a strength of grip that astonished me. "to you, sir, shall be entrusted the double mission of opening communication across the western boundaries with our mexican allies, and of negotiating with the present spanish authorities for the santa fe trade. i need hardly mention to a man of your intelligence that such projects as we contemplate are not carried to completion without funds. to me falls the task of collecting the sinews of war."

"to me the leadership of the scouts!" i cried. "i am doubly hot to take the road. dawn shall see me in the saddle!"

"the fire of youth!" he exclaimed, again clasping my hand. "go, make your preparations. you will ride none the less swiftly that you carry a packet of letters for me."

"willingly!"

"you think to go south to new orleans?" i bowed. "then a letter as well to daniel clark."

"i am known to him."

"true; but i have word to send him—no less to wilkinson—regarding the death of pitt."

"it is months since that event," i remarked. "the prime minister died in january."

"the post to louisiana is uncertain. wilkinson at least may not have heard, and i have comments to make. you will deliver the letters for me?"

"i should be pleased to do so, sir. it is a small enough favor to undertake, even for a chance acquaintance."

"but a favor that shall be remembered, doctor. your lodging?"

"the plow inn."

"the packet shall be in your hands by evening," he replied.

i rose at the words, and he showed me to the door, with repeated assurances of confidence and esteem.
