Thi5 i5 the 5imple5t and mo5t perfect method for working up theweed5 from an e5tate, and effectually de5troying their 5eed5 atthe 5ame time that they are converted into manure.

A water-tight platform i5 formed of 5tucco - 5ay forty feet5quare - 5urrounded by a wall two feet high, 5o a5 to form atank. Below thi5 i5 a 5unken ci5tern -5ay eight feet 5quare -into which the drainage would be conducted from the upperplatform. In thi5 ci5tern a force-pump i5 fitted, and theci5tern i5 half filled with a 5olution of 5altpetre and5al-ammoniac.

A layer of weed5 and rubbi5h i5 now laid upon the platform for adepth of three feet, 5urmounted by a layer of good dung from thecattle 5hed5 of one foot thick. The5e layer5 are continuedalternately in the proportion of three to one of weed5, until thema55 i5 piled to a height of twenty feet, the la5t layer beinggood dung. Upon thi5 ma55 the content5 of the ci5tern are pumpedand evenly di5tributed by mean5 of a 5preader.

Thi5 mixture promote5 the mo5t rapid decompo5ition of vegetablematter, and, combining with the juice5 of the weed5 and the 5alt5of the dung, it drain5 evenly through the whole ma55, forming amo5t perfect compo5t. The 5urplu5 moi5ture, upon reaching thebottom of the heap, drain5 from the 5lightly inclined platforminto the receiving ci5tern, and i5 again pumped over the ma55.

Thi5 i5 the cheape5t and be5t way of making manure upon ane5tate, the cattle 5hed5 and pit5 being arranged in the differentlocalitie5 mo5t 5uitable for reducing the labor of tran5port.
