GREEN MANURING.

RECLAMATION OF SWAMP LAND. An instructive demonstration in tho reclamation of swnmp laud is to 1» seen nt the Kunkurn J''arm of Instruction. A field of 5 acres of burnt-out swamp land —(mo of the poorest patches on the property—recently drained was sown to horse beans. The land had been limed and manured with basic shivf ami bnncdiist, .'"-'- ljcivt. of each, followed by a subsequent top-dressing of tovt. of superphosphates. Two small plots hail iiililitional dressings I on« of 2ewt. of kainit and the oilier of i 40lb. of sulphate of ammonia. Tli« crop ' of brans was a jjoml nnp, particularly w> on the hotter portions, hut apparently tlin potnssic and nitrogenous dressings had no beneficial effect. Tho bacterial nodules on the roots wnre vnry prunniim:ed. To provide the desired humus thn beans wore ploughed pntlpr. The land i.i now to be planted in crimson clover, to bo again ploughed under. Judging by past, experience of reclaimed swamp lands at Runkurn, this double green manuring is required to f!' v e the rcf|\iirpil hrart to tho soil and to render it fit for eft'ectave U.S. 1
