are essential to the construction of nil till ellos silos and without which silage will not be kept lu in perfect condition 1 the walls should be airtight since bince the keeping of silage depends upon the exclusion of air it Is imperative that the walls of the silo be built in euch such a way as to keep out tho the air the lumber debould be well matolee ma toLed and that containing large knots should bo be rejected in concrete silos a wash on the inside with cement or with raw coal tar thinned with gasoline Is ef of in ia making the walls impervious to air care should be taken that the doors fit closely into their frames 2 the walls should be smooth and plumb so that the silage will not ad here to them in settling and thus cause air in the outer edge of the silage furthermore the walls should hould be capable of standing consid erable rable lateral strain without cracking or bulging this is one reason why rectangular silos are unsuccessful 3 the ello silo must be deep enough so that the pressure from above will thoroughly rack pack the te silage and force ou out t the air mr tin greater the pressure the tho less air lu the silo 11 and the less will be the loss oc of
