Nozzles. Of the nozzles in use the various forms of the Vermorel

It must be borne in mind in the use of any pump, no matter how 

 well constructed, that it is liable to get out of order and the manip- 

 ulator should fully understand the construction of every part and be 

 able to put boxes and packing in repair when out of order. After 

 using, clear water should always be run through the pump before it 

 is put away.

One of the greatest obstacles to the successful use of fungicides 

 and insecticides has been that of keeping the solid particles of the 

 mixture in suspension so that a uniform quantity can be put on all 

 parts of the trees or plants sprayed. To overcome this difiiculty 

 many appliances have been made to agitate the liquids so that these 

 particles should not settle, but most of them have been failures.
