Show CONCRETE AND TILE SILOS ARE DURABLE DUR-ABLE WHEN PROPERLY C0NST0CTE0 An anonymouB bookrot, ovidently prepared to dlscourago farmers from building concroto and tllo silos, has recently been circulated In Bomo parts of the country. The booklet consists of photographs ot cracked and cot apscd bIIos, and tho examples shown represent what may happen when concrete nnd tile sites nro Improperly Im-properly constructed, but thoy should not bo used tu discredit these types ot silos. Whonover farm buildings nro not permanently located, or If for other reasons a temporary structure Is do sired, tho wooden silo may bo preferred prefer-red to ono of concrete or ot other durable material. Whore lumber Is cheap, or where stono and gravel can not bo tcndlly obtained, the first cost of n wooden silo may bo less than that of n concroto silo. Hut for n permanent structuro It is generally best to construct of tile, concrete, co-iicm co-iicm block, or somo other durable material. Silos properly built of theso materials aro not Ukoly to bo damaged by winds. Thoy must bo properly reinforced, however, or thoy will crnck and eventually fall down In somo cases tho cacklng of tho concrete silo Is Caused by too small a proportion of cement usod In Its construction. Moro often, howovor, tho troublo Is duo to Improper reinforcement rein-forcement ABldo from tho matter of rolnforclng, most of tho failures ot concrete silos havo boon caused by poor nnd insufficient foundation. The concrete silo should bo built with a solid wall six Inches thick und rolnforced with steel rods or wovon wlro fencing. Tho Joints In each courso of tho wlro fencing should overlap and tho ends bo tied. It Is sometimes stated that tho si lago next to tho wall will spoil for a distance of six Inches. If tho si-lago si-lago Is not well pajked and if tho Inside walls aro left rough, It will spoil nt tho edges, but this may happen hap-pen In nny typo of silo. If tho Inside In-side walls nro comparatively smooth and coated with raw coal tar thinned thin-ned to tho consistency of pnlnt, and tho silo Is properly filled, tho silage will keop In good condition for bov-oral bov-oral years. Tho Impossibility of moving Is another an-other nrgument which has been used against concroto alios, but a man who builds for permanenco nnd has n llvo stock business definitely established es-tablished has no occasion for moving mov-ing tho silo. Somo concroto and tllo silos havo been properly constructed and lm- Hisisl proporly filled, but theso are not suf- ficlont reasons for condemning thoso Bl types of silos. Tho unqualified as- lll scrtlon that tllo, concroto, cement '1 block nnd brick silos nro not durable . jlH Is not based on facts. lsisisfl Dotal s for constructing wooden iHI nnd concroto silos may bo obtained Sfcisisfl by applying to tho Dopartment of Ag- III rlculturo. ial |
