A GENERAL VIEW 5 



for this purpose. This phase of vegetable forcing will 

 become more and more important as the wealthier classes 

 become acquainted with the superiority of greenhouse 

 products. 



(4) By erecting small greenhouses, 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

 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
