Table 6. — Third-generation offspring, from alcoholized grand-parents. 

 Fertility records of non-alcoholic trained offspring (A)2 of alcoholic grandparents compared 

 with corresponding trained normals (N)2. Matings of the two sets were made at the 

 same age and records of births taken during equal periods. 



Dr. Abert F. Blakeslee reports on his work in plant genesis at the 

 station as follows: 



"Most of my research has been devoted to breeding and selection work 

 with the adzuki beans which we are carrying on under the auspices of the 

 National Research Council. In addition to the lines which we have had in 

 cultivation for several years, some 40 new lines have been secured from Dr. 

 C. V. Piper, of the Bureau of Plant Industry of the U. S. Department of 

 Agriculture, and have been grown under test conditions. We have about 

 8 acres of adzukis under cultivation at this station and in addition have dis- 

 tributed seed for trial to correspondents in 52 different localities. Most of 

 these correspondents are in agricultural experiment stations. Professor 

 Hartil, of the New York State School of Agriculture at Farmingdale, Long 

 Island, is cooperating in the work and has grown in test plats representatives 

 from 38 different pure lines. When the harvest records are in from our own 

 plantings and from plantings away from the Station, we shall be in better 

 position to judge of the adaptability of the species to cultural conditions in 

 this country. 



"Adzuki beans seem to be immune to anthracnose, a disease destructive of 

 the navy bean; but unfortunately certain lines at least seem susceptible to 

 bean 'mosaic,' which is common in New York State on various races of 

 Phaseolus vulgaris. It is possible that immune races of the adzukis may be 

 discovered. A disease, probably due to the fungus Fusarium, brought in 

 perhaps by soya beans, with which we have surrounded our breeding-plats as 

 a protection against rabbits, has caused trouble in parts of the garden. 



"Disorganization of the gardening staff due to the war has somewhat 

 handicapped the work of the department. Mr. Avery was called by the 

 selective draft late last year. Mr. Farnum served as temporary gardener 

 for about 3 months and Miss Minns has been acting gardener during the 

 summer. While both have carried on their individual work satisfactorily, 

 it has necessarily taken some time for each to become familiar with the 

 special crop under cultivation. Mr. Welch, my laboratory assistant, was 

 taken by the draft early in July and Miss Conover has been engaged to fill 

 his place. 



"In addition to the disorganization of the work due to the changes in 

 assistants, difficulties in growing and hybridizing the adzuki beans under 

 glass have been encountered and much time has been lost in consequence. 

 It has been discovered that they will not thrive in the greenhouse during the
