GERMINATING PLATE, of graniteware, 11 inches in diameter by 1% inches deep. For use 

 with moist blotting paper in germination experiments $0.35 



GERMINATING TRAY, of water-proofed wood, 25x25x2% inches deep, for testing fertility of 

 corn and other grain. A frame which fits into the tray is divided into 144 squares- which 

 may be numbered if desired. (For illustration, see preceding page) 5.50 



GERMINATING TRAY, of wood, 18x10x2 inches deep 2.00 



GERMINATION OR SPROUTING APPARATUS, Schoenjahn's Patent, for quickly determin- 

 ing the percentage sprouting value of barley, showing its malting quality. Equally efficient 

 in showing sprouting value of all grains. Capacity, 100 grains. Complete with directions 

 for use 7- 50 



GERMINATION OR SPROUTING CUP, as described in Bulletin No. 35 of the Rhode Island 

 Experiment Station, and on page 14 of Bailey's "Nursery Book." Of porous clay 3 inches 

 in diameter by 1% inches high, with ventilated cover and glass dish 50 



GERMINATION TESTER, Sho-Gro, oil heated, constructed throughout of non-rustable metal 

 and glass. It has a capacity of 5 trays, each measuring 10x15 inches, so that a large number 

 of samples may be accommodated at one time. The outside measurements over all are 32 

 inches high, 13 inches wide, and 17 inches deep. Since all sides are of glass, the progress of 

 the test is always in view. Complete with 24 blotters, a supply of dividing- strips and oil 

 lamp for heating 15.00 



GERMINATION TESTER, Sho-Gro, same as No. 7336, but electrically heated, with switch for 

 three heats 23.00 



In ordering, kindly state voltage of circuit. 



GRAIN' CONTAINER of galvanized iron, see Bins and Containers. 



GRAIN OR SEED SCALE (Dirt Scale), for ascertaining the percentage of dirt in grain or 

 seed. The beam has two rows of marks, the upper indicating the weight, one pound by quar- 

 ter ounces; the lower the percentage of dirt. In use a sample pound is weighed, sifted, and 

 replaced in the scoop. The poise is th*n run back until the beam balances. The lower row of 

 marks shows the percentage of loss by dirt removed, i. e., the percentage of dirt contained in 

 the seed. Complete with brass scoop 12.00 



GRAIN TESTER, Grobecker's, of nickeled brass, for determining rapidly the farinaceous con- 

 dition of barley and malt. Fifty kernels may be cut through at a time 9.00 



GRAIN TESTERS, of best construction, highly polished and lacquered. When the cup is empty 

 the beam balances with the poise set at zero. Beam has three rows of graduations which 

 indicate the number of pounds per bushel of sample, the exact weight of sample, and the 

 percentage of loss in cleaning.
