for this purpose. This phase of vegetable forcing will 
become more and more important as the wealthier classes 
become acquainted with the SpE nce of greenhouse 
products. 
(4) By erecting small echt: primarily for start- 
ing early vegetables for outdoor planting, which are large 
enough to yield a profit in the forcing of vegetables when 
the space is not otherwise in demand. 
(5) By the construction of very large ranges for the 
sole purpose of growing and maturing vegetables out of 
season. The owners of many of the largest establish- 
ments are also market gardeners, who utilize a small per- 
centage of the greenhouse space for the starting of early 
plants. 
Organization.—The vegetable-forcing interests of the 
United States are fairly well organized. In 1908 the 
Greenhouse Vegetable Growers’ and Market Gardeners’ 
Association of America was organized at Cleveland, Ohio. 
A few years later the name was changed to the Vegetable 
Growers’ Association of America. While the society has

gardening, the forcing interests have received much 
attention because many of the members have been promi- 
nent growers of vegetables under glass. This organiza- 
tion is one of the strongest horticultural societies in 
America, and it is exerting a strong influence upon the 
development of vegetable forcing. 
The .widest field for organization, however, is in the 
development of co-operative associations. These have 
been formed in many of the most important forcing 
centers, and it is hoped that the movement will continue 
until every district is organized. 
The following are some of the advantages or benefits of 
co-operation: (1) Educational. The strongest associa- 
tions hold regular meetings, in which methods are dis- 
cussed and the entire industry considered. (2) One of
