bright, otherwise the lighter shade, if it is clear and bright, will 

 be preferred. That is to say, the brightness of color is of more 

 importance than the shade." 



To sum up, the chief requirements of an Improved Yellow 

 Eye bean are : that it must be relatively large and of sufficient 

 depth of color to contrast strongly against the clear opaque 

 white background. 



In Fig. 40 are shown some of the variation from the standard 

 type of Improved Yellow Eye against which there is at the 

 present time no discrimination in the market In Fig. 41 are 

 shown a few of the types which the dealers do not want and 

 which on the average will not bring the best prices. 



One other point should be mentioned in connection with 

 these beans. This is the uniformity of the product not only 

 of each grower but of each community or better of the State as 

 a whole. It is obvious that in order to secure fancy prices a 

 man must not only have some beans of the standard type, but 

 he must have them all of that type. The more nearly uniform 

 and true to type the better price one can expect for his crop. 

 When it becomes known that a community is producing a 

 standard uniform type of bean, the dealers will be willing to 

 pay a better price for the product. 



Of the various types of Yellow Eye beans the Improved, 

 or as it is sometimes called the Boston Yellow Eye, is by far 

 the best seller in the Boston market. There is more demand 

 for this bean than for any other type of Yellow Eye. Conse- 

 quently growers of this variety are always assured of a ready 

 market for their crop. 



According to our experience the type of Improved Yellow 

 Eye described above is of the short runner type of plant. 

 Under ordinary conditions the runners are from 2 to 3 feet 

 long. Where the beans are grown in a field by themselves this 

 is an advantage in that it gives opportunity for a larger yield. 

 Where beans are grown in with corn, however, this is a dis- 

 advantage, since in harvesting the beans the corn is likely to be 

 injured. One of the objects of the Station's breeding . work is 

 to produce a good yielding standard Improved Yellow Eye of 

 the bush type.
