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."
