As a general result, the following values were obtained for the 

 loss occurring under various conditions.

The loss, therefore, may vary, according to the character of 

 the manure and the manner of handling, from 0'8 to about 10 

 times that amount. Roughly speaking, the loss should generally 

 be well under half a ton per truck. The legitimate loss, however, 

 is often increased by the manner of weighing the trucks, for these 

 are not uncoupled for the purpose, and the weighings are often 

 taken while the train is in motion, so that what is recorded as the 

 weight, is really the kick of the beam, and there is a drag down- 

 wards from the coupling irons at both ends of the trucks.
