100 INTENSIVE FARMING 



a greenhouse product which has been developed 

 for a special purpose and which is not well 

 suited for outdoor conditions. 



The most noteworthy examples of special 

 purpose varieties are to be found among the 

 cucumbers, melons, and tomatoes which have 

 been developed by English and European gar- 

 deners. The great length of the English forc- 

 ing cucumbers, the superior texture and flavor

 striking characteristics. As a further proof of 

 their distinctive characters none of these sorts 

 are as valuable when grown in the open as the 

 ordinary field sorts. 



High Protein Corn. The work of Dr. Hop- 

 kins at the Illinois Experiment Station clearly 

 demonstrates the possibility of developing ce- 

 reals with! distinctive qualities. The protein 

 content of corn has been decidedly increased 

 and correlations have been established which 

 make it possible to determine by observation 

 the kernels which possess more than the nor- 

 mal protein content. 



The development of high sugar content in 

 the sugar beet is a striking instance of the abil- 

 ity of breeders to develop and establish special 

 qualities in plants. The beet normally contains
