Improved Lettuce Stocks 
After devoting several years to SINGLE plant 
selection we are offering many improved strains 
of Lettuce, each of which is the progeny of a 
single plant. 
Each year we are hybridizing many hundred plants 
of the leading varieties, with a view to obtaining 
NEW SORTS and to IMPROVING EXISTING 
TYPES. 
Our Lettuce crops are rogued by experts as many 
as four times while growing, and there are no 
purer or more highly bred Lettuce stocks produced 
than those which we are offering.
