ably the largest factories are these of Kellar and Thomason Manufacturing 

 Company at Los Angeles, and the Pomona Manufacturing Company at 

 Pomona. The prices given below are for California. The first firm will 

 deliver their appliances at Vancouver for the same prices as quoted for 

 California points and for orders amounting to $1,000, a discount of 10 per 

 cent, is given, but to this the duty of 33 per cent, must be added. No doubt 

 the second firm would give about the same prices.

5. Pressure Pipe Lines and Valves. 



On some of the orchards in the Okanagan and Grand Forks districts and 

 also on orchards in Idaho and southern California, the water is distributed 

 over the orchards in high pressure, wood-banded pipe lines. The pipe lines 

 take the place of the head ditches; they are tapped at each row or wherever 

 desired by a standpipe formed by screwing in the wood short sections of 

 galvanized iron pipe capped by an ordinary garden valve to regulate the 

 flow. Where the land is very irregular and it is desired to keep the water 

 under pressure, this form of construction is the most desirable and in fact 

 the only feasible one, but if it is possible to break the pressure and main- 

 tain it within the safe pressures for cement pipes by proper regulation, the 

 cement pipe distributing system has the advantages of lowest cost, greater 

 durability and better division of the water between furrows.
