The Success Silo. 



Since designing the Iowa silo, it has been learned that tile 

 blocks have been used for silo construction in Ohio for at least 

 six years. Success silo is constructed from patented blocks. 

 These blocks are heavier than the common building block and 

 they are laid on end. The walls are made strong enough to 

 resist the pressure of the silage by the use of a U shaped key of 

 the same material as the block which slips over the end walls and 

 is just large enough to lie between the two partition walls of 

 the block above, thus doubling the strength of a single bond. 



The Section obtained the names of the owners of 26 of 

 these silos and sent a letter of inquiry to each, obtaining 20 

 replies. In every case the owners were pleased with their silos. 

 Some of these silos have been in use six years and were reported 

 in as good condition as when first erected.
