ADDITIONAL ILLUSTRATIONS OF SPRAY PUMPS AND 

 OTHER MACHINES IN USE FOR THE DESTRUCTION 

 OF INSECTS. 



The object of includiug in Part II. of the Handbook additional 

 illustrations of the various spraying pumps and other insect-destroying 

 machines now in use either here or in other countries, is that farmers, 

 fruit-growers, vignerous, and others may be able by aid of the figures 

 and descriptions to select for themselves such articles as appear best 

 suited for their requirements; and as our rural population is in some 

 districts scattered, and so far removed from the great centres of popula- 

 tion, it has been thought desirable to furnish some particulars as to cost, 

 &c., as also names and addresses of firms from whom the machines may 

 be obtained, taking them in the order in which I have received the 

 particulars from the owners or agents, the author of each article or 

 description being responsible for the statements contained therein. 



A good spraying apparatus, if it is to last, should be carefully looked 

 after, and immediately after use must be cleaned out, dried, and clear 

 water forced through the nozzles before these are laid by and again 

 used.

 {See Figs. 1, 2, and 3.) 



A spraying arrangement which will operate in a wholesale manner 

 has recently been invented by Mr. A. N. Pearson, Government Agri- 

 cultural Chemist, in connexion primarily with the work of the Inter- 

 colonial Rust in Wheat Conference. 



From the drawings it will be seen that the arrangement consists of 

 an iron tank, (or other suitable vessel), placed in an ordinary cart; 

 attached to the top of this tank is a pump (either a rotatory or double 

 acting piston pump), which is operated by means of chain gearing and 

 spoke clamps on the cart wheel. This pump, when the cart is in motion, 

 draws the liquid out of the tank and forces it into a long pipe or system 

 of pipes bearing a number of atomizing nozzles, through which the 

 liquid is ejected in a fine spray. 



The invention consists principally in the use, arrangement, and manner 

 of support of the long pipe or system of pipes. The pipe is made in 

 sections, which can be screwed together in a variety of ways. In 

 Fig. 1, all the sections are arranged in the form of a long horizontal 

 pipe, 50 feet in length, supported, firstly, by two standards clamped on
