_29th._--Before day-light we were up and making ready for Saltillo. As we passed through Monterey, much attention was attracted by our numbers and healthy appearance. Having traveled fifteen miles we arrived at the little town St. Catharine, situated near the mountain in the pass. It contains about five hundred inhabitants. Near us on the same route, are encamped three companies of regulars. I suffered but little from this day’s march; and felt that I could go twice the distance on the succeeding day, with as little suffering as I endured some of the first days. The garden of General Arista near Monterey, must have a passing notice. It certainly surpasses anything of the kind that I ever beheld. It is regularly laid out with taste and skill. The earth is raised about three feet above the walks. Here are flowers of all varieties and the most fragrant. On each side of the main path (which is made of plaster, white and smooth), are two large basins with fountains rising from the centre. But more beautiful still are two pools of water, the most limpid and transparent, in which may be seen myriads of the finny tribe. Then there is a clear cool stream flowing through white cement tunnels, throughout the whole garden. The shady groves of exotic fruits, the atmosphere laden with grateful perfumes, all conspired to make it a place of enchantment. Everything appeared so novel, so beautiful, that I almost fancied it the Garden of Eden. _30th._--Here we are encamped in the plaza of Rinconida, after a most fatiguing march of twenty-two miles. The road was broken and rocky, and the wind blowing to the rear nearly suffocated us with dust. This town is built of mud, and is half way to Saltillo. To this the armistice extended. Rinconida signifies secure corner, and is in keeping with its name, being in the intersection of two ranges of mountains. It could be well defended by a small force. Tending to and from the town is a beautiful grove of trees, forming a shady archway above, and is interspersed with enormous century plants, the stalks of which rise from fifteen to twenty feet. Quite an excitement! Arrival of the Great Western, or, the heroine of Fort Brown. She has every appearance of an Amazon, being tall, muscular, and majestic in her expression. She won laurels at the bombardment from Matamoros. She issued out coffee to the men while the bombs were falling all around her. _31st._--On the morning of the 31st, we were mustered for two months’ pay; then took up our line of march as usual. Owing to the well nigh broken-down state of our teams, we marched but twelve miles on the 31st. The road was hilly and dusty, but we arrived at our encampment in good time; the Greys being the advanced guard. This place is called the Warm Springs, from the temperature of the water. It is destitute of tree and bush, for miles around, that could be procured for fuel. “_Camp Butler, Jan’y 1st, 1847._ “DEAR SISTER:--
