Potash Fertilisers

These German Salts of Potash have been introduced into this country, and some sales have been made. We are informed that these salts now sold here are not genuine Leopold shall Kainit, but adulterated or calcined and ground with other materials. Only one person, Otto Radde, has the exclusive privilege of exporting these salts from Germany, and a guarantee goes with each lot sold, from him. We are experimenting with the lot now imported and sold here, and will investigate the yalue of them.

Potato

We have devoted several pages in the present, and last number, to the complete account of the Dioscorea batatus, respecting which short paragraphs have conveyed, from time to time, more or less information. The first article is credited to the London Mark Lane Express, which is the exponent of subjects on food; the present number contains an account of its cultivation taken from the new Patent Office Report, and will be found full and interesting. The trials yet made of this esculent in this country, are not yet conclusive as to its importance, but there seems to be every probability of its adaptation to our climate and soil; if so, it will become of the utmost importance, and not improbably the prairie land of the West will become its home*

Potomac Fruit Growers' Association

This is comparatively a new society, or, at least, has only become prominent within a late period. An interesting discussion on blackberries and raspberries was held at Washington recently, and among other things said and done, Mr. Saul remarked:

If I were going into the blackberry culture I would not confine myself to any one, but would raise the Wilson, Kittatinny and Missouri Mammoth. There is none that is superior to all others. My experience, however, is that here the blackberry is not a paying crop. The wild fruit is so fine and abundant as to prevent the sale of the cultivated variety at paying prices. The Wilson is with me two weeks earlier than the Kittatinny.

Poudrette And Guano

DEAR SlR: As I notice that you endure questioning very patiently, I beg leave to propose one or two for answers in the Horticulturist for March. I wish to know:

1. Whether the Poudrette of the Lodi Company, 74 Cortland-street, New York, is to be depended on, and is worth " $2 a barrel, or $1.50 for any quantity over six barrels;" what crop it is best adapted to, what quantity to be applied, etc.

2. The same information relative to the Bone dust and Peruvian guano advertised by New York dealers. Yours. J. M. Winchell. Syracuse, N. P., Feb., 9, 1852.

Poughkeepsie Horticultural Society

There is an active Society at this place, which holds frequent meetings for the discussion of horticultural subjects, and seems thereby to be doing much good. We had their proceedings, but they were mislaid. We should be glad to have them again.

Poultry And Eggs

Have our readers any idea of the annual value of poultry and eggs in the United States? The value of poultry in 1840 was estimated at more than twelve millions of dollars, and three years later at twenty millions. It is estimated that the city of New York expends yearly a million and a half in the purchase of eggs alone.
