SIZE OF POTATO SETS. 
23 
The data in Table 9 show, as in the case of the Irish Cobbler, that 
the largest total yield was produced by the 6-ounce whole tubers 
and that even after deducting the seed used the yield was considerably 
greater than its nearest competitor, the 4-ounce whole, which came 
second. The 3-ounce whole tubers came third. 
Table 9. — Comparative yields from Green Mountain potato sets of different sizes 
at Caribou and Presque Isle, Me., in stated years. 
[Inthe columns headed "Yield of primes, net" the quantity of seed planted has been deducted, making
