He threw a peeble at them, and it would be hard to imagine, he says, concentrated in so small a space, so much expression of defiance, fury, and ability to do mischief, as the pleasant little colony presented. From the 1st to the 9th of November, we find frequent mention in the "Notes" of an extraordinary species of cactus, to which Dr Engelmann of St Louis, in an interesting botanical letter appended to Mr Emory's work, proposes to give the name of _Cereus Giganteus_. Under this name we find it depicted at page 96, in a plate where a mounted Indian, halted at its base, gives, by comparison, an imposing idea of its height. It also forms a most singular and striking feature of several of the landscapes scattered through this volume--of one particularly, on the Gila, where it has the effect of a chain of artificial columns or signal-posts. One of its most curious characteristics appears to be its invariable perpendicularity both of stem and branches; the latter, as soon as they bud out from the main trunk or from each other, hastening to turn their heads heavenwards, and to spring up in an exactly parallel direction to the parent stem. "The stem," says Dr Engelmann, "is tall, 25 to 60 feet high, and 2 to 6 feet in circumference--erect, simple, or with a few erect branches." Mr Emory's first mention of this pillar-like plant is as follows:-- "At the point where we left the Gila, there stands a cereus six feet in circumference, and so high that I could not reach half way to the top of it with the point of my sabre by many feet; and a short distance up the ravine is a grove of these plants, much larger than the one I measured, and with large branches. These plants bear a saccharine fruit much prized by the Indians and Mexicans. They are without leaves, the fruit growing to the boughs. The fruit resembles the burr of a chesnut, and is full of prickles; but the pulp resembles that of the fig, only more soft and luscious. In some it is white, in some red, and in others yellow, but always of exquisite taste."
