sufficient length to contain all of the varieties. The rows were 

 70 centimeters apart, and the hills stood 50 centimeters apart 

 with two plants in a hill. The soil was first plowed and then 

 worked into a mellow consistency by means of hoe and rake. The 

 plants were cultivated regularly twice each week. The plant- 

 ings were made on May 11, 1916, and there was sufficient rain 

 so that irrigation was not necessary. Fj seed secured from the 

 first plantings was used. 



The results obtained from project 4 were disappointing. Only 

 six of the sixteen varieties of beans matured any seed what- 

 ever. Neither the Tepary nor the Henderson's Bush Lima pro- 

 duced any pods. Both of these varieties shot their pods when 

 young, because of fungus attacks. 



Practically all of the varieties of P. vulgaris were severely 

 attacked by the bacterial disease caused by Pseudomonas phaseoli. 

 The pole varieties were much more resistant, and a few seeds 

 were saved from a few of those that were apparently free from 

 the disease. It was not possible, however, to save any mature 

 seed from any of the bush varieties. The Hodson's Green Pod, 

 the Longfellow, the Extra Early Refugee, and the Lady Washing- 

 ton all failed because of the attacks from the bean maggot. 



The yields were in all cases much below what would be a satis- 

 factory garden production. The Kentucky Wonder, the Cana- 

 dian Wonder, and the Southern Creaseback gave mediocre yields, 

 but the Southern Prolific came near failing entirely. In most 

 cases there was a slight decrease in the size of pods and in 

 some cases in the size of the ripe bean. 



PROJECT 5. WET SEASON 



Project 5 consisted of the plantings of fifteen varieties of 

 beans in my home garden, all being Phaseolu^ vulgaris. One row 

 was given to each variety, the rows being 10 meters in length. 

 The rows stood 50 centimeters apart, and the hills were 40 centi- 

 meters apart with one plant in a hill. All varieties except two 

 were planted on May 8, 1916, the two exceptions being planted 

 on May 21. F^ seed secured from the first plantings was used. 



Every variety experimented with project 5 started out very 

 promisingly. The bean maggot gave very little trouble, and 

 even with a bacterial disease severely attacking every variety, 

 each gave a fair yield. The disease attacked the pods of all 

 varieties to such an extent that it was practically impossible 

 to secure any ripe seeds whatever.
