Bone Dust

Mr. Cummings, the agrioulturalEditor of tlio New Yojjf Observer, says : "Wheii entering upon the cultivation of our present farm, we askod our predecessor what field would give a erop of pntatoes without the applieation of' iresh baruyard manure, as we feared the applicatión of such as inducing the rot. A fivo-aere field was namcd. We carefully planted and cultivnted it, and found no rot among the potatoes, but the yield of the whole field did not supply the tables of tho farm for the year, so exhausted was the land. In the autumn wo plowed and sowed the same field with rye, applying twenty-five bushels of bone dust to the aere. Such was the imraediate effect of tüe applieation, that whon the rye wns grown, a aiao of ordinary stature would be coneealed by the cro.p ia walking through the field. Grass seed was sown with the rye. A good erop of hay was taken tha first year it was mowed. - But tho secoud year, when turf was well established, sixteen tong of hay were taken from the fivu acres. After movviog it four years, it was plowed ncd planted to corn, giving a heavy erop without inauure. Such is our experience in the uae of bone as manuro. Bono dust by the quautity uosts aa to the quality from 50 to 70 cents por bushel. Tweuty to twenty-five bushols of bone is a good dressin" to the acre, and ia wortli from two to three times the oost of stable manure brought from the city. Bone dust should be applied to and left is near the surfuee us may be, and be suitably cuvered. We usually sow broadcast af ter tho first harrowing.. The teoond course of the harrow will cover near the surface."
