A somewhat novel yet benevolent project, for the amelioration of the condition of poor orphan girls, is now under consideration. It is proposed by Mrs. T. W. Phelps, of Irving Place, who has generously donated an extensive and suitable plot of ground near New York for the purpose - to establish a horticultural school, where young girls may learn such light and healthful branches of industry as are embraced in the growing and canning of all the finer fruits and vegetables, the care of hothouses, the breeding of birds, the rearing of fowls, etc. Prosperity attend the attempt to teach young ladies something useful!

Soda Ash is considered one of the most valuable agents, when dissolved and diluted, that can be used in the nourishment of plants. Four pounds and a half of ashes, with three pints of quicklime, placed in three gallons of hot water, stirred occasionally, and allowed to remain for three or four days, will make, when diluted with rain water, 192 gallons of manure, that may be applied with the greatest confidence to kitchen-garden crops, and soft-wooded flowering plants in the pleasure garden. It is suitable for light, sandy soils, and its effects are steady, certain, and lasting; but in using it for vegetables it will be advisable not to apply it to seed, nor until the seedling plants have expanded their second leaf. Then it may be given to them in the evening, after the sun is bid behind the hills, or when he is overcast, and the day is likely to continue so throughout, or when rain is falling from the clouds; then the watering-pot may be taken, and the ground drenched with the liquid, so as to be likely to reach every fibre. This I practise two, and, in some cases, three times a week.

It is, perhaps, one of the most suitable liquids that can be given to cauliflower, endive, and celery plants, as it does not, like those of a more stimulating nature, induce prematurely the elongation of the flower-stem; at the same time it leads the plants to the full development of their character, except in cases where the seed has not been of the right kind.

An experiment which was tried on the 12th of last July, upon the green fly, which had literally covered the plants of endive that formed a row across one of the beds in the kitchen garden, should be related. The plants were in a healthy condition but a few days previous to the fly being discovered upon them, but on the day mentioned above they looked sickly and dirty. Destruction to the whole of the plants appeared certain unless they could be divested of the destructive Liliputian army which was feeding upon their blood. Having proved the effects of soda ashes as an insect destroyer in one particular instance, I determined to try their qualities upon the fly, and, if possible settle them with it, even should it be at the expense of the plants. I therefore took eight gallons of soft water, and added soda ashes sufficient to make it six times stronger than that which is stated above, and in the evening took the watering-pot without the rose, and poured the whole of the liquid all over the tops of the plants; and, to my gratification, the following morning the plants were alive, and not a living fly upon them. They were syringed with clean water, and from that time until they were removed from the ground, they received no check in their growth.
