 Fast walking horses should be given the preference. 



To reduce as much as possible the cost of removing

 this method of transportation is available.

 other words, the grease in one ton of garbage is worth 

 about two dollars. The other ingredients are worth 

 a little as a basis for fertilizer. Reduction works are 

 almost always owned and operated by private com-
