In that one little corner of California is found a species of mining which is seldom or never mentioned in print. It is called “pocket mining” and I am not aware that any of it is done outside of that little corner. The gold is not evenly distributed through the surface dirt, as in ordinary placer mines, but is collected in little spots, and they are very wide apart and exceedingly hard to find, but when you do find one you reap a rich and sudden harvest. There are not now more than twenty pocket miners in that entire little region. I think I know every one of them personally.

From Chapter 58 of Roughing It:

"Something very important happened. The property holders of Nevada voted against the State Constitution; but the folks who had nothing to lose were in the majority, and carried the measure over their heads. But after all it did not immediately look like a disaster, though unquestionably it was one I hesitated, calculated the chances, and then concluded not to sell.

At 12 15 P.M., crossing Laramie's Fork, a fine clear stream about forty yards broad, we reached Fort Laramie — another "fort” by courtesy, or rather by order— where we hoped to recruit our exhausted stores.

...the clouds of grasshoppers. According to Lieutenant Warren, whose graphic description is here borrowed, these insects are “nearly the same as the locusts of Egypt; and no one who has not traveled on the prairie, and seen for himself, can appreciate the magnitude of the swarms. Often they fill the air for many miles of extent, so that an inexperienced eye can scarcely distinguish their appearance from that of a shower of rain or the smoke of a prairie fire. The height of their flight may be somewhat appreciated, as Mr. E.

The habitat of the prong-horn antelope (Antelocapra Americana, called "le cabris” by the Canadian, and “the goat” by the unpoetic mountain man) extends from the plains west of the Missouri to the Pacific Ocean; it is also abundant on Minnesota and on the banks of the Red River; its southern limit is Northern Mexico, whence it ranges to 53° N. lat. on the Saskatchewan.

Wednesday, July 31.—Sunrise. Court House Rock, Chimney Rock, and Scott’s Bluffs, in sight. At noon passed through Scott’s Bluff’s pass., 580 miles from St. Joseph. This was the first high ground, since entering upon the plains. All was vast, prairie, until we reached Fort Kearney. Soon afterwards, we struck the barren region, and thenceforward we had a level expanse covered with sage brush, and that was the character of the growth until we arrived here, the plains being more or less elevated, or broken, but in other respects preserving the same characteristics.

At 12 45 P.M., traveling over the uneven barren, and in a burning sirocco, we reached Lodge-Pole Station, where we made our "noonin.” The hovel fronting the creek was built like an Irish shanty, or a Beloch hut, against a hill side, to save one wall, and it presented a fresh phase of squalor and wretchedness. The mud walls were partly papered with “Harper's Magazine," “Frank Leslie," and the "New York Illustrated News;" the ceiling was a fine festoon-work of soot, and the floor was much like the ground outside, only not nearly so clean.

This occurred west of Alkali Station:
