and the plants were placed 14 in. ae in the rows, an 
covered by about 3 in. of soil. The first shoots appeared ‘above 
ground on May Ist, and from that time the plants grew vigor- 
ously. go actntap up a little guano was sown between the 
rows but no other manure was given. 
About aie middle of July, and again during the second week 
in August, they were sprayed with Burgundy mixture but the 
tops did not show signs of disease. In “both cases the haulms 
were very vigorous 
Lochar was lifted on September 15th, and yielded 197 lbs. of 
tubers. The largest tuber weighed 131 ozs., and there were 
many between 8 and 10 ous. ‘There were 27 lbs. below seed size 
and 12 small tubers were diseased. Many tubers were affected 
with scab. Of the five large uncut tubers one was cut 
into two equal pieces at planting time, the others being planted 
whole. There was no difference at lifting time between the 
Kerr’s Pink was lifted 0 on x Bapteuey 22nd and each root was 
weighed separately. The total yield was 157 lbs., the heaviest 
root yielding 7 Ibs. 13 oz. Two other roots yielded 5 lbs. and 
5 Ibs. 10 ozs. respectively, whilst other 10 rocts produced 4 Ibs. 
or more each. Sixteen roots bore bed 3 and 4 lbs. each and 
but two roots yielded below 1 Ib. each. Those two roots were 
always rather weak and the tops were eventually killed by their 
stronger neighbours. They produced but 6 and 7 ozs. respec- 
tively. The heaviest tuber weighed 15} ozs. and there were 
many tubers between 9 and 13 ozs. Seven pounds were below 
seed size. Seventeen tubers were affected with ordinary potato 
disease, and many were marked with common scab in the 
same way as all the varieties of potatoes grown on the same 
ground. 
More room ought to have been allowed both between the rows
