SEEDAGE. 



10. The Geneva seed-tester. 



an apparatus devised at the New York Agricultural Experi- 

 ment Station, and which has been found so satisfactory as to 

 supersede all other sorts of germinators at that institution 

 for general use. It consists (Fig. 

 10) of a pan 10x14 inches wide 

 and 3^ inches deep, to be cov- 

 ered with a pane of 

 glass. Along the 

 sides is a ledge 

 ;Hrinch wide, and as 

 much below the upper 

 edge. The pan is 

 best made of tinned 

 copper, the ledge 

 formed by the proper 

 shaping of the sides 

 of the pan, and the 

 edges on three sides 

 turned over to form 



a groove into which the pane of glass may be slid from 

 one end. These details are not shown in the cut. The 

 seeds are held in the folds of cloth. A strip of white 

 Canton flannel is taken sufficiently wide so that when 

 hemmed on both sides (to prevent seeds slipping out of the 

 ends of the folds) it will be the same as the inside width of 

 the pan. A long enough strip is used to have about twenty- 

 four folds i> inches deep, and leave a flap of several 

 inches at each end. The upper margin of the folds is 

 sewn across to permit a J^-inch brass rod to be run in 

 (Y, P), from which the cloth is suspended in the pan, as 

 shown in the cut. The lower margins of the folds (o) are 

 also sewn across to make them stay in place better. The 

 total length of the strip after the sewing is completed is 

 about a yard. Two such strips are used in each pan. 



' ' To put the pan into use, it is filled part full of water, 

 two of the prepared cloths put in, the glass cover adjusted 

 and the whole boiled over a lamp for a short time. This is
