Greenhouse and Field Tests being conducted at Henderson's Greenhouse Plant and Trial Grounds, Red Bank, New Jersey 



THE HENDERSON FOUR WAY TEST 



Back in 1817, Peter Henderson adopted as the guiding factor of his business, the principle of Tested Seeds. This principle was the result 

 of his own practical experience as a market gardener. He originated many of the methods of seed testing still used today. During the years 

 that followed, his sons Alfred and Charles adhered strictly to the guiding principle and now his grandson, Peter Henderson, has increased the 

 value of our slogan Tested Seeds, and has further safeguarded the interests of our customers by instituting the Four Way Test. ■.. ; . . 4 



To the usual laboratory tests for purity and viability — the greenhouse tests for germination — the Trial Grounds tests for trueness of type 

 as fixed by the Henderson Standard of Perfection — there has also been added the production tests, where results are subjected to actual market- 

 ing conditions. In this way it is possible for us to keep our finger on the pulse of consumer demand, and consequently permit us to specialize 

 in such varieties of seeds that are most in demand, and will produce the most profitable crops for our progressive Market Grower customers.
