Wm. R. and Eliza Smith, of Macedon, N. Y., have devoted nearly their whole time during the fruit season the present and past year, in perfecting their process for preserving soft and perishable fruits in glass jars, in a fresh state, like that when first taken from the tree. Their mode consists substantially in expelling the air from the jars by heat, and then heremetically sealing them; but there are so many minute particulars to be attended to, that one who should remain a whole day in their laboratory, and closely observe every part of the process, would not probably succeed as they do, after a month's trial. In truth, one might as well think to draw a fine picture without experience, by watching for a few hours the brush of an eminent artist. They preserve strawberries, cherries, raspberries, peaches, plums, pears, tomatoes, Sec.; and so different are the details of the process for each of these, that the necessary requirements for one sort, would, if applied to others, entirely spoil them.

Of their fruits prepared last year, when they had much less experience, some proved imperfect by losing a part of the peculiar fresh flavor of newly plucked fruit, while other specimens which we examined, and more especially the clingstone peach-es, could hardly be distinguished from those of yesterday's ripening. They are particularly successful with tomatoes, the flavor of which, after months of keeping, we much prefer to that of the specimens which are usually brought early in summer from the Island of Bermuda. They have now on hand a large collection of far or bottles for distribution, and we hope they may reap some reward for the extraordinary labor, skill, and ingenuity which they have be-stowed in perfecting their process.
