therefore be seen that the liquid must carry itself 

 twenty -five to thirty feet beyond the nozzle. For 

 such purposes, a nozzle which distributes the liquid 

 in a spray directly from its orifice is of small use. 

 A nozzle must be had which throws a more or 

 less solid stream, and the stream should break up 

 when it reaches its destination. It will therefore be 

 seen that it is practically impossible to secure a 

 single nozzle which is best for all purposes. The 

 grower should have at least two styles, one for 

 short range and one for long range. The Cyclone 

 types of nozzles are generally best when a very 

 fine spray is desired for short range (consult 

 Fig. 70). 



Remarks similar to the above may be made for 

 pumps ; that is, there is no one best pump. We 

 might divide all pumps into two general classes, 

 those which deliver the liquid by force of gravity, 



NOTE. The pictures of spraying machinery (Figs. 70 to 75, pages 362 to 367) 

 are inserted only for the purpose of familiarizing the reader with a number of 

 the different types of inventions which are useful in the work. They are not 

 inserted for the purpose of recommending any of the devices, and there are 

 many other machines, which are not shown in the engravings, which are 

 equally as good.
