Dr. Wm. B. OsboRN, one of our subscribers, and the agent of the Horticulturut in Los Angelos, California, thus writes to Col. B. P. Johnson, Secretary of the New York State Agricultural Society. Mr. Osborn has sent us a goodly number of subscribers, and we should be much gratified if he would occasionally give us notes of the progress of horticulture in his new home.

"I have almost forgotten what winter was. I have been from New York seven years; and here perpetual spring and summer has lost to me many of the charms of a New York winter. I feel chilly when I think of it - eight months fire in the house. Our horses and cattle mow and secure their own fodder without the assistance of man. Snow we can see, when we east our eyes to the Sierra Nevada, but it is never a near neighbor. We raise here, in our little valley, the fruits of both torrid and temperate zone?. Id the same garden, side by side, grow the Apple and Orange, the Pear and Lime, the Peach, Fig, Olive, Grape, Luna, Pelair, Apricot, and Pomegranate. We have here a few Americans, who are doing much to improve the culture and varieties of all kinds of fruits. The native Californians still claim that their old mode of culture is superior to any novidad of the eetrangtro*. I have been a resident of this city since 1847, and one can not but be pleased with the changes for the better which have taken place. Some of these, it is true, have been violent; but now all is quiet, and person and property are secure.

I should be pleased to exhibit some California implements at one of your State Fairs".

A New York Gentleman who devotes much attention to gardening matters, writes as follows:

"I see in your last number some inquiries about mulching Strawberries with tan. Your cor-respondent, I think, lost his plants. He laid it on too thick. Three incliee of tan will generally produce fermentation and burn the plants up. Not more than one inch should be used under any circumstances. The best mulcher, according to my experience, is a highly tempered steel rake, with prongs at least eight inches, applied at least once a week daring the season. While on this subject, let me say to you that I am now engaged in testing all the leading varieties of Straw, berries. I propose to do the thing up thoroughly; submitting them to the best treatment, and making notes daily of every thing I see. When I have finished this branch of the subject, I shall take the best kinds and submit them to various trials of manures, etc I shall probably be occupied several years with the subject* and then I hope to be able to write the natural history of the Strawberry, as it has never been written before. I began this spring; and now have upwards of thirty varieties, having procured most of them from original sources, to insure correctness".
