The Evolution of the Silo in HILE the silo had its origin in RR] Europe, the evolution of the mod- ern silo with which all are so familiar has “been a distinctly American process. The first silos were simply deep cellars or pits in which 'the green corn Wasi‘packed and weighted down with a covering of boards, straw and earth, or some similar substance to exclude the air and 5pack the silage together, as was then thought necessary to prevent it from Spoiling. But the labor of getting the feed out of these pits was not a task to appeal to American farmers, and had it not been for the improvement of the silo through a natural process of evolu- tion, the silo would not be so common an equipment upon the ayerage farm as it is today, even if the advantages of Silage as a succulent winter feed were as well understood and as generally appre— ciated as they now are. It is interesting to note that the first introduction of the silo into American agriculture was by a Michigan man, it being said upOn good authority that the first silo in America was built in \Vayne county, by Dr. Manley Miles, formerly of the Michigan Agricultural College. Not- withstanding that early introduction of the silo into Michigan agriculture, the growth of its popularity was slow for many years. Thisfact was due partly to a natural conservatism of the farmers with regard to adopting a radically new method of this kind for the storage of valuable feeding stuffs until it had been thoroughly tested out and demonstrated to be an efiicient method, but perhaps to an even greater degree to the imperfec- tions and disadvantages of the earlier types of silos with which we are fa- miliar. ,The first silos to be constructed after the idea of the pit in the ground was abandoned were built above ground in the same form as the old pit; that is to say, they were square. in shape, generally being constructed of lumber with a dou- ble ceiling on the inside to make them as air tight as practicable. They were not as high as thOSe built today, which fact, together with the square shape, pievented the silage f1 om settling as com- pactly as it does in the modern silo, and notwithstanding the fact that the old method of putting a feeds was the chief factor in populariz- ing the silo and stimulating the work of progreSSch manufacturers and the ap— plication of American inventive genius to this problem. One of the first essentials in the mod- ern development of the silo was the de- velopmen_t of machinery by which the corn could be cut and elevated into the silo. \\'ith the adoption of the above- ground form of construction, the silage cutter with an elevator attachment was the first development, but the introduc- terial available upon the farm and in a crude way as compared with the modern silo of this type. But to the 'manufac- lurers belongs the credit for the devel- opment of this most popular and useful type of silo to its present day perfection, with many exclusive features of value and of material and workmanship which insure a degree of permanency which, with reasonable care, will extend beyond the life time of the owner. Silos of more permanent material were also constructed rather early is the evo- tion of blower elevators, which facilitatedlution of this farm necessity. Silos ol' Well Located Stave Silo and New Barn the convenience in filling taller silos, with the simultaneous development of the round type'of silos, were factors which may be considered as most important in the evolution of the silo in America. The first of the round silos were, like the square ones, of home-made construc- tion and generally with the double lin- ing of lumber, but as this form of silo was in reality nothing but a huge tank, manufacturers of wooden tanks soon de- veloped the stave silo. This form of silo was also to some extent built out of-ma- on Farm of C. R. Taylor, Oakland County. stone and brick, and later of concrete, were built, and where the foundations were adequate and the workmanship good some of these structures gave excellent service. But of modern developments in the use of permanent material for silo bilding, none is more important than that of the adaptation of vitrified hollow tile to this use. Silos of hollow tile were first bilt from ordinary building tile and hooped like wooden silos. But here again the manufacturers rose to the occasion and brought out special tile for this pur— America. pose, adapted to the circular torm of silos and with special provisions . for doors. At one stage in the development of this form of silo dependence was placed upon the tensile strength of the vitrified tile, but later steel reinforcement was ad- ded in a manner to provide adequate, in- surance against cracking or
