After dinner, Houston returned to the office in company with Morgan and the expert, two new characters which he was studying attentively. The former was a tall, raw-boned individual, with a genial, good-natured manner, but a weak face; one who would willingly be a tool for any villain, but an unreliable tool. He would betray his best friend, and knowing nothing of honor himself, he did not believe in its existence, among men or women. To him, all men were rogues, all business simply gambling on a large scale, and his only care was to be on the winning side. Haight was a small, dark man, with soft, insinuating manner, and, in accordance with his pet theory that every person, high or low, rich or poor, might sometime be useful to him in the furtherance of his own objects, he treated every one with punctilious politeness. To some his manner might have been pleasing, but to one with any degree of penetration, the crafty, scheming nature under the thin veneer was very apparent. Meanwhile, Rutherford had rather reluctantly accepted an invitation from Mr. Blaisdell to go through the mills and visit one or two of the less important mines. The young easterner was soon much interested, as, after having explored one of the smaller mines, the Peep o'Day,--which he thought very appropriately named as he glanced upward from a depth of a few hundred feet,--he was taken to the mills, and there saw the various stages through which the ores pass in the process of reduction. He almost forgot his dislike of Mr. Blaisdell as he listened to his explanation of the different classes of ore, and the various kinds of treatment which they required, and met some of his old college acquaintances,--the sulphates, nitrates, carbonates, and other members of that numerous family,--in new and startling array; for Mr. Blaisdell was thoroughly at home in chemistry and mineralogy, and enjoyed nothing so much as airing the knowledge he possessed in that one direction. Of other branches of science, and even on subjects of general information, he was profoundly ignorant, although blissfully unconscious of the fact. Rutherford was next shown the method by which the ore ready for shipment was conveyed down the mountain to the cars on the spur tracks, hundreds of feet below, by means of a rail tramway on trestle work, some three thousand feet in length, having a grade of nine feet per each hundred feet, over which cars of ore were passing, operated by gravity, the weight and velocity of the descending, loaded car, carrying the empty car upward. He thoroughly enjoyed these novel scenes, and congratulated himself upon the many picturesque mining views which he would add to his collection.
