and connected by flexible connections. At 

 intervals of every few lengths of pipe a three- 

 way cock is inserted, to the outlet of which is 

 attached the rubber hose. The three-way cocks 

 can be set to shut the supply off entirely or 

 open to the main or the hose only. The first 

 length of hose branches into two further lengths, 

 to the ends of which are attached the spraying- 

 branches and nozzles. The pipes of which 

 the main consist are made of specially light 

 galvanized steel tubing, so that a man can carry 

 from four to six lengths at a time, and when 

 the area at the end of the main has been sprayed 

 the supply can be turned off at the nearest 

 three-way cock and the piping out of use shifted 

 to a new area. 



With this system a large acreage can be 

 sprayed (or irrigated) in one day, and the plant 

 can also be used for ordinary pumping purposes 

 for water supply, &c. 



One word in regard to the Weeks' Patent 

 " Multi-Spray " nozzle which the firm supplies 

 with the machines. It is an exceedingly in- 

 genious arrangement, which enables the grower 

 to obtain any kind of spray he may desire, 

 between the finest and softest mist and a 

 long powerful drenching jet. It is adjusted 

 by merely turning the cap and has clear 

 passages, so that it is practically unchokable. 

 The advantages of using this nozzle will be 

 apparent, as it combines the uses of three or 

 four of the ordinary pattern, and is adaptable 

 for all purposes.
