The road passed over to-day was good, but the face of the country exceedingly rugged, bro- ken, and covered with pinch and cedar. To the left one or two miles distant, towers a wall nearly perpendicular, 2000 feet high, apparently level on the top, and showing as Iiear as 1 could judge from the road, an im- mense stratum of red sand stone.———p. 29. “Aug. 18. Four or five miles from the old Pic-as, the road leads into a Canon, with hills on each side from .1000 to ‘.3000 feet above the road, in all cases within cannon shot, and many within the point blank mus- ket shot.———p. 31. ' “ The geological formation much the same as before described, until you begin to de- scend towards the Del Norte, where granitic rocks and sand are seen in great abundance as far as Santa Fe. Cedar pinch, and a large growth of long leafed pine are densely crowded wherever the rock offered a crevice, -—until within or 8 miles ofthe town. “(Santa Fe).-——On leaving the narrow valley of the Santa Fe, which rises from 1000 feet to a mile or two in width, the country presents nothing but ‘barren hills, ut- rterly incapable, both from soil and climate, of producing anything useful. The valley is entirely cultivated by irrigation, and is now covered with corn. Five miles below the town, the stream disappears in granitic sands.——p. 34. “ Sept. 2. We descended the valley of the Santa Fe river nearly west for 5 miles, when we left the river and struck across a dry arid plain, intersected by dry beds of streams. Twenty-three miles brought us to the G-alisteo_ Creek, which at that time was barely running. From this place to its mouth there is scarcely the sign of vegetation. At the dry mouth of the Calisteo and directly on the Del Norte, is the town of Santo Do- mingo.——-p. 36, “The valley of the Del Norte is here quit narrow and the soil sandy.~—p. 38. a “Sept. 3. Between San Filippe and the Angosturas, six miles below, the valley of the river is very narrow, afibrding no inter- val for agriculture. On the west side, the banks are steep walls, crowned by __seams of basalt,’forming the table land. The east is composed of rolling sand hills, rising gradu- ally to the base of the mountains, and co vered with large round pebbles. Elevation, 5000 ieet.——p. 39. ’ “Sept. 4.

About 11 o’clock the whole character of the night was changed byan east wind that came rustling down fromithe mountains,driving the sand before it.

Camp near Secora——leave the river and strike for the Gila. We accord- ingly moved only 6 miles to-day, and en- camped a little north of Secora, preparatory to taking the hills to-morrow. The prospect is forbidding; from Sierra Lescadron, oppo- site the amphitheatre, as far south as the eye can reach on the western side of the river, is a chain of precipitous basaltic mountains, traversed by dykes of trap , through these we are to pass.——p. 51.

The river corn- rnences to gather its feeble force into the smallest compass to work its way around the western base of Fra Cristobal mountain.— The Chihuahua road runs on the eastern side, and that part of it is the dreaded “jor nada” of the traders, when they must go most seasons of the year 90 miles without water. Our road over hill and dale led us through a great variety of vegetation, all to- tally different from that ofthe United States. To-days observations of the plants maybe taken as a fair specimen of the southern part of New Mexico‘. First, there were cacti in endless variety, and of gigantic size ; our new and disagreeable friend, Carrea Mexicana, Fremontia, &c. i The table lands, reaching to the base of the mountains to the west, are of sand and large round pebbles, terminating in steep bills from a quarter to a halfa mile from the river, capped with seams of basalt.———-p. 54. “Oct. 9. The country becomes broken, and the valley narrows into a cannon which sweeps at the base of Fra Cristobal moun- tain, making it necessary to rise to the table land on the west side, which we found tra- versed by deep arroyas, crowned on their summits by basalt.-——p. 54. “The road was unbroken, obstructed by bushes, and so badgthat the wagons made only 11-; miles, and the teams came into camp blown and staggering, after their day’s larly.

After going a few miles, cross- ing and recrossing the river a dozen times, it was necessary to leave its bed and avoid a canon. This led us over a very broken country, traversed by hugh dykes of trap and walls of basalt. ’ “ The earth in the river bed, where it was not paved with fragments of rocks, was loose resembling volcanic dust, making it unsafe to ride out of the beaten track. A mule would sometimes sink to his knee. This was a hard dry day on the animals, the steep ascents and desccnts shifting the packs, and cuttingthern dreadfully. The howitzers did not reach the camp.-—p. 62. “ Oct. 23. Last nightthe heavens became overcast, the air damp, and we expected for the first time since leaving Santa Fe (0. month tomorrow) to have a sprinkle of rain ; but at 9 this morning the clouds had all cleared away. “ The changes of the temperature are very great,owing to the distance from the influ- ence of large masses of water, and if they are accompanied with corresponding changes in humidity, they would be insupportable.—— Last night we went to bed with the ther- mometer at 70° and awakened in the morn- ing shivering, the thermometer marking 25°. “The table land, 150 feet above the river, was covered so thick with large paving peb- bles, as to make it diflicult to get a smooth place to lie upon.
