Adam Weaber & Son, Yineland, N. J., are also the mak- 

 ers of some excellent spraying machines. One of their 

 nozzles that will be found convenient to use in con- 

 nection with a number of machines of various makers, is 

 shown in the above cut. 



I wish to acknowledge the kindness of the various firms 

 above mentioned, in loaning us the cuts here used to illus- 

 trate machines.
