Hundreds of Leading Orchards 
Under Observation Constantly 
Every Owner Glad to Cooperate in this Merciless Search for 
Greater Quality and Productivity 
Every year, through hundreds of leading orchards, 
whose owners gladly cooperate with him, there walks 
a man—notebook in hand—searching eagerly for trees 
of outstanding perfection. 
This man is Roy E. Gibson, head of our Research 
Department, who, under the direction of Charles E. 
Greening, perfected the principles of Greening Bud 
Selection. To quote from a letter received from Mr. 
Stanley Johnson, Superintendent of the Michigan State 
Experiment Station, South Haven, Michigan, “Mr. 
Gibson is, I believe, the keenest orchard observer I 
have ever met.” 
It is Mr. Gibson’s duty to select from trees with the 
highest performance records those parent trees from 
which buds are taken for the propagation of Green¬ 
ing Super Selected Fruit Trees. Only those trees that 
have produced fruit of superior quality, size, color, 
shape and uniformity—and in highly profitable volume 
—are selected for this purpose. 
Each tree is given a number, painted on the trunk, 
and a record is kept for a number of years before any 
propagating buds are taken. A complete record of 
every Greening Super Selected Parent Tree is kept on 
file in the “million dollar library,” available for inspec¬ 
tion in our offices. 
State Horticultural Colleges and Experiment Sta¬ 
Roy Gibson and Brooks D. Drain, of Massachusetts State College, 
on an Orchard Inspection Trip 
tions, leading pomologists, horticultural societies, and 
fruit growers everywhere are giving Greening their 
whole-hearted cooperation and support in this impor¬ 
tant work of orchard improvement.
