SATISFACTION GUARANTEED 
We are located in the heart of the New York Cut Flower Market. We have nine men on the road travel¬ 
ing extensively in nearly all sections of the country. Our position, for over 28 years, has been one of daily 
contact with the grower and his needs. 
This catalog, we believe, is full evidence in itself of our long established plan to render a complete service 
to the grower in a full line of Seeds, Bulbs, Plants, Cuttings, Insecticides, Fertilizers, etc. At all times we 
invite inquiries as to prices and all other information.
