The witness's voice, raised by suggestion of counsel to a higher note, came athwart Mocket's speculations. "I listened to Colonel Burr's mode of indemnity; and as I had by this time begun to suspect that the military expedition he had on foot was unlawful, I permitted him to believe myself resigned to his influence, that I might understand the extent and motive of his arrangements. Colonel Burr now laid open his project of revolutionizing the territory west of the Alleghany; establishing an independent empire there; New Orleans to be the capital, and he himself to be the chief; organizing a military force on the waters of the Mississippi, and carrying conquest to Mexico—"

On went Eaton's disclosures, punctuated by heated objections from Wickham and Luther Martin, and once or twice by a scornful question from Burr himself. It was damning testimony, and the throng hung breathless on the various voices. Mocket listened also, but listened with his eyes upon his chief, and when there arose some interruption and dispute over technicalities, his freed mind proceeded to deal with Rand's change of aspect. It occurred to him to wonder if the light which showed it to him could be falling through a veil of storm cloud, but when he glanced at the high window, there was only the blue August heaven. What, then, gave Lewis so dark a look? "The black dog he talks of has got him sure," thought Tom. "What's happened to anger him like that?"

The voice of the witness again made itself heard. "Colonel Burr stated that he had secured to his interests and attached to his person the most distinguished citizens of Tennessee, Kentucky, and the territory of Orleans; that the army of the United States would act with him; that it would be reinforced by ten or twelve thousand men from the above states and territories, and that he had powerful agents in the Spanish territory. He proposed to give me a distinguished command in his army; I understood him to say the second in command. I asked him who would command in chief. He said, General Wilkinson. I said that General Wilkinson would act as lieutenant to no man in existence. 'You are in error,' said Mr. Burr. 'Wilkinson will act as lieutenant to me—'"

Mocket moved with care along the ledge until he had brought within his view another portion of the Hall. "That look of his isn't fixed on nothing! Now we'll see." He stood on tiptoe, craned his neck, and surveyed the crowded floor. "Humph!" he remarked at last. "I might have known without looking. If I were Ludwell Cary—"

The counsel for the prisoner and the prisoner himself were subjecting the witness to a riddling fire of cross-questions. Mocket, on his coign of vantage, was caught again by the more apparent drama, and looked and listened greedily. Eaton at last retired, much damaged, and Commodore Truxtun was sworn. This was a man of different calibre, and from side to side of the long room occurred a subtle intensification of respect, interest, and attention. On went the examination, this time favourable, on the whole, to Burr. "The prisoner frequently, in conversation with me, mentioned the subject of speculations in western lands, opening a canal and building a bridge. Colonel Burr also said to me that the government was weak, and that he wished me to get the navy of the United States out of my head; that it would dwindle to nothing; and that he had something to propose to me that was both honourable and profitable; but I considered this nothing more than an interest in his land speculations—"

The August heat was maddening. Now and then a puff of wind entered from the parched out-of-doors, but it hardly refreshed. The flutter of the women's fans in the gallery made a far away and ineffectual sound. "All his conversations respecting military and naval subjects and the Mexican expedition," went on Truxtun's voice, "were in event of a war with Spain. I told him my opinion was, there would be no war, but he was sanguine of it. He said that after the Mexican expedition he intended to provide a formidable navy; that he meant to establish an independent government and give liberty to an enslaved world. I declined his propositions to me because the President was not privy to the project. He asked me the best mode of attacking the Havana, Carthagena, and La Vera Cruz—"

The day wore on. Truxtun was released, and the Attorney for the United States called Blennerhassett's servants to prove the array at the island and the embarkment upon the Ohio. They did their best with a deal of verbiage, of "Colonel Burr said" and "Mr. Blennerhassett said," and with no little bewilderment under cross-examination. "Yes, sir; I'm telling you, sir. Mr. Blennerhassett allowed that Colonel Burr and he and a few friends had bought eight hundred thousand acres of land, and they wanted young men to settle it. He said he would give any young man who would go down the river one hundred acres of land, plenty of grog and victuals while going down the river, and three months' provision after they got to the end; every young man must have his rifle and blanket. When I got home, I began to think, and I asked him what kind of seed we should carry with us. He said we did not want any, the people had seeds where we were going—"

"Of what occupation were you upon the island?" demanded Mr. Wirt.

"A gardener, sir. And then Mr. Blennerhassett said to me, 'I'll tell you what, Peter, we're going to take Mexico, one of the finest and richest places in the world!' He said that Colonel Burr would be King of Mexico, and that Mrs. Alston, daughter of Colonel Burr, was to be the Queen of Mexico whenever Colonel Burr died. He said that Colonel Burr had made fortunes for many in his time, but none for himself, and now he was going to make something for himself. He said that he had a great many friends in the Spanish territory; that the Spaniards, like the French, had got dissatisfied with their government, and wanted to swap it. He told me that the British also were friends in this piece of business. I told him that the people had got it into their heads that Colonel Burr wanted to divide the Union. He sent me to Mason County with a letter, but I wasn't to deliver it until I had the promise that it should be burned before me as soon as 't was read, for, says he, it contains high treason."

"Gad!" thought Mocket to himself, "I'm glad that some one else's letters are burned as well! If I were as cool as Aaron Burr looks—"
