These figures were only general, and were subject to 

 a 10 per cent discount, and since the weight of the tiles 

 depends upon the character or specific gravity of the 

 clay from which the tiles are made and also upon the 

 thickness of the walls of the cylinder, they must not be 

 taken to apply to particular cases. Where one wishes 

 to figure the cost of transportation on tiles from any 

 given factory, he should learn the exact weight of the 

 tiles of that particular brand or make. In sending some 

 distance for the tiles, quotations should be secured from 

 the railway or water transportation company for the rate 

 per ton for freight ; or the different factories bidding on 

 bills of tiles should be asked to quote prices, including 

 the freight, at the farmer's home station. 



Quality of drain tiles. There is a great difference in 

 the quality of drain tiles from different factories, and 

 even of the individual tiles from the same factory or kiln. 

 In ordering, one should buy by sample, or on the guar- 

 antee of a reputable firm. Where the purchaser can visit 

 the factory, judgment can be passed on the quality of the 

 tiles. They should be straight and square on the ends 

 so as to come close together in the ditch. When two 

 tiles are knocked together, they should have a clear ring. 

 Cracks in a hard tile are objectionable, but much worse
