362 The 7 rials of Corn and Seed Drills, 1912. 



The seed was rather indifferent, in that it was not as clean 

 as it mio-ht lia\p been. Imt it wns tlie same for all. 



FIG. 3— Kell & Co.'s H.C. "John Bull" 13-row Corn and Seed Drill, Class I. 



This test proved rather severe on some of the competitors. 

 Messrs. Martin's exhil)it. provided with a new worm forced 

 feed, slipped its gearing several times, and the beans jammed 

 in the worm feed wheels, and ultimately the machine retired 

 from this run. The "Superior" also showed some difficulty 

 in adjusting the coulters to even distances, and also in getting 

 the seed in at uniform depths. It clearly showed the supe- 

 riority of the old " cup feed " over any other form of feed 

 exhibited. 



Regularity of distribution by individual coulters was next 

 tested. For this purpose a small canvas bag was attached to 

 each coulter, and with a supply of peas the machines were 

 driven over a length of 200 yards, sowing into the l)ags at the 

 rate of 3 bushels per acre. On weighing the bags it was found 

 that :—
