On the 7th of last October, a large agricultural lair was held at Sacramento, which was quite an affair. An address was on that occasion delivered by Dr. John F.

Y.,) Mr. Shelton, of California, stated that Indian corn did not generally flourish in California. It grew to an enormous height with small crops, from 20 to 25 feet high, at least. The climate is exceedingly changeable. Mr. S. said that he saw some Canada corn four to six feet high, the ears being near the ground. The westerly winds rush in at San Francisco, and rarify the hot air in the valley where stands the city. The branches of trees are all bent to the eastward. Various trees are so injured by wind and sand that they become stuntedjand grow up in a bush form. As soon as the rainy season be gins, clover commences to grow, and grows very bushy and tender. The Indian Squaws gather baskets full, every day, making a kind of beverage of it. The hills and valleys are covered with wild oats and clover. The cattle and stock get very fat on these oats and clover. The clover comprises some filteen or twenty varieties of every hue and color. The grasses are very fine ; the native timothy yields from two to five tons per acre. It is ten feet high. The pin grass is of a very curious growth. An acid clover grows very abundant in the valleys ; the natives make a lemonade of it ; it is very healthy. He gathered one bushel of sour clover weighing 31bs. The Rev. Mr. Filch, of California, stated that vegetation began in November, and dried up in June. Drought continues till November, and generally without dew. The people commence cutting barley about the last of May, and let it lay on the ground over two months, not raked up.
