THERMOMETER, graduated from to 200 Centigrade, specially designed for moisture test- 

 ers $2.00 



AUTOMATIC OIL MEASURING AND GRAIN SEPARATING DEVICE, consisting of a gal- 

 vanized iron tank, re-enforced strongly with brass, and so mounted on brackets that it can 

 readily be attached to any of the moisture testers; fitted with a measuring device which 

 automatically measures out 150 cc of oil into test flask by merely pushing the neck of the 

 flask upward against an automatic catch. The cover of the tank is fitted with a funnel- 

 shaped sieve, which catches the mixture of grain and oil as it is poured from the flask after 

 the test, and strains- the oil into the container below. In this way the oil is kept free from 



dust and dirt, and the same oil may be used repeatedly 5.00 



FANS, Sample, of aluminum; for use in sampling and inspecting grains, with one end formed 

 into a spout for pouring out contents. Strong, light, and well made; will not rust or tar- 

 nish; upward pitch of spout prevents grain from rolling out. Recommended in Bulletin No. 



99 of the Bureau of Plant Industry. Size 9x6x1% inches each 1.40

 termination Apparatus. 



SAMPLER, Bag, for sampling small seeds in sacks. Diameter, % 2 inch; length, 4% inches 1.10 



SAMPLER, Bag, similar to No. 7382, but for grains. Diameter, % inch; length, 6 inches. . . 1.50 



SAMPLERS, Grain, consisting of two polished brass tubes, one fitted inside of the other, and 



having openings matching each other. By turning the handle, the inner tube is revolved,

 inch round perforations; a scalper sieve with i% 4 inch round perforations; and a chess sieve 

 with perforations 4%/64 by % inch. (See Regulatory Announcement No. 22 of Federal Wheat 

 Grades effective July 1 and August 1, 1917) 8.00
