REMARKS. By clear days is meant that no clouds were visible at the times of observa. tion; by cloudy, that some were visible; and by rainy days, that some rain fell, without reference to quantity. The heaviest rain of the year commenced falling at noon on the 27th of February, and continued, without intermission, until 10 P. M. of the 28th, measuring 2.10 inches. The last rain of the past season occurred on the 17th of June, 1854, and amounted to 0.20 inch. The first rain of the present season was on the 4th of October, when 0.14 inch fell. Thus far the present has been a comparatively dry season. The Sacramento River remained at a very low stage until the 15th of March, when it rose 20 feet 2 inches above low-water mark; since which time it has been gradually falling. The 13th of July was the hottest day experienced during the year, and indeed since the settlement of the country. The thermometer was observed, in some less favored situations than ours, at 1070 at the hottest time of the day. The mean temperature of the hottest part of the day for the week ending July 15th was 970. The night of the 16th of August was the hottest as yet noticed in the country; the thermometer standing at 820 at 10 P. M., and 700 at sunrise. The weather during the whole Winter was mild, dry, and pleasant, and the Spring opened early. On the Ist of February the Cowslip was observed in profuse blossom on the surrounding plains; on the 15th, the Wild Violet; on the 20th, the Peach-tree; and on the 23d, the Willow (Salix nigra), and the Nemophila, a small indigenous blue flower.
