Northrup, King & Co.’s Seed Production Fields are 
carefully inspected and rogued by trained plantsmen. 
The seed is then tested under gardening conditions 
in our trial grounds—and finally tested for germina- 
tion, vigor and purity in our modern seed testing 
laboratory. We try in every way to supply highest 
quality seed.
