 A recent estimate by Emerson yields the following results:

The standai'd of oOU bushels of i)otaloes [)ci- acre is ad-

 precision in fertilizers and culture methods, this standar<l 

 mioht be raised to 1000 bushels, possiblv, w ithont increasing 

 per-acre cost of opehition, except to pick up the additiomri 

 500 bushels. Probably Lord liosebcry holds the world's 

 record: 2053 Inishels of potatoes — 1754 marketable and -!•'.>

 our scale of elliciency falls to 4 j ])er cent. 



Hills of potatoes vary remarkably in the sanu- liidd. and 

 beghniings have been made in '' hill selection ol .srtd on this 

 account. Tubers planted from strong hills have thus been 

 found to yield as hiHi as sixteen times as many jHiunds as
