"You refer, sir, to the Northwest Expedition under the command of Captain Lewis and the brother of Clark of Vincennes fame."

"The furtherance of unremunerative scientific research is one of the few functions properly within the scope of an ideal government. I am hopeful of valuable results from this expedition as regards the advancement alike of geography, botany, zoölogy, and mineralogy."

"I trust, sir, that you will be equally gratified by the results of the exploration of the Mississippi by my friend Lieutenant Pike."

"Pike?—Pike?—Ah, the son of Major Zebulon Pike of the Revolution. General Wilkinson duly informed the Secretary of War that he had sent young Pike up the river with a small party. But it is a purely military expedition, equipped by the General on his own initiative; although I may add that his action in the matter has since received the approval of the Government."

"That last statement, sir, is of no little satisfaction to myself as a friend of Lieutenant Pike. I am sure that he will quit himself of his service with no small credit. Allow me to speak of him as one of the Republic's most able and patriotic young soldiers."

"So I have been informed. On the other hand, the young man lacks the scientific attainments most desirable in the leader of such an expedition."

My heart gave a bound that sent the blood tingling to my finger-tips.

"Mr. President," I exclaimed, "the Government is doubtless aware that General Wilkinson has in view another expedition,—one to proceed westward to treat with the tribes of the great plains and to explore the western boundaries between Louisiana Territory and New Spain. I am, sir, only too well aware of my lack of standing alike with the General and with the Government, yet I believe I can say, with all due modesty, that I possess somewhat the scientific attainments you mention as desirable—"

I stopped short upon meeting the growing reserve in my companion's mild gaze. He smiled not unkindly.

"I did not state, Dr. Robinson, that such attainments were the sole requisites. Moreover, this expedition, if in truth such a one is contemplated, rests wholly upon the discretion of General Wilkinson, and will no doubt be of a military character."
