In an interesting series of experiments receutly made on the farm of the Roynl Agricnltnrnl Society of England, the manuriill vahie of snit was unmistakably indicated. An acre of wheat dressed with 300 pounds of common salt yielded thirty-nine bushcls of grain, with a proportionato amotint of utraw ; wliifa ia adjoining aore, left unmunured, produceel only twenty-nine bushel.s per aero, with the straw imporfectly develojied. The entire cost of the erop is not stated, lmt tlie rxperiïaent sliows that the additional ten bushels resultinK from the salt were pcoduced at a oost öf 'io cents each. In another case pieoe of groiind intended fov wheat wms I.;vci! the preceding fall, and agaiu in May, when it was sówed with sált; ted afterwarfl jjlowed 'ling. On the lst and 2d of êeptember wheat was Rown ít the i;ate of two biishels to the acre. The erop, when harvestud, yielded, aceording to 0)6 estímate tf the gwner, M. John Park, [not loss than forty Imshels of grain to the aero, with a luxuriant growth of straw. Fi-oin these and many gimilar cases tho inferonce seems to be that salt is :i specific for tlio 'hcat erop, imparting solidity to the gram and finimess to the stray. Hut it must not be eoiicluded that equiilly good resulte will alwajH follow the itpplication of Montreal Gasette.
