(2) "Some three or four years ago, when I was living in 

 Barbados I had as a visitor Dr. S. C. Harlarid, of the Cotton 

 Research Station, St. Vincent. He expressed some interest in 

 this subject, and going no further than my small garden we found 

 seed capsules in abundance, though neither of us had noted them 

 before. On his return to St. Vincent, Dr. Harland found them 

 abunda,nt in his own garden, and raised some 26 seedlings, 

 recorded in the Annual Report of the St. Vincent Agricultural 

 Department for 1919, page 9. I have no reason to believe that 

 this was in any way exceptional and from the great mixture of 

 varieties that occurs in the fields I believe that seed production 

 is pretty regular in the Windward and Leeward Islands. "^ — Wm. 

 ^ Nowell, Assistant Director, St. Clair Experiment Station, 

 Port-of-Spain, Trinidad. 



Trinidad. "In Trinidad I am informed that the sweet 

 potato does not seed. The plant is not so much at home in our 

 humid climate as in the other islands and gives low yields. I 

 think it probable, however, that seed could be found if looked 

 for, but the present is not a suitable season to verify this belief."

 Station, June 16, 1922. 



Hawaii, (i) "In regard to the sweet potato blooming and 

 setting seed in Hawaii I would state that there are a number of 

 varieties and hybrids thereof grown by us on the University 

 Farm which seed freely. On the other hand, not all varieties 

 seed and especially during moist seasons when the foliage de- 

 velops most luxuriantly and even the seeding varieties are less 

 inclined to seed during wet years. When hand-pollinated a 

 good many sorts set seed which would not seed of their own 



^ account." — F. G. Krauss, Professor of Agronomy, University of 



^ Hawaii. 



(2) "The writer has been undertaking the improvement of 

 sweet potato by sexual breeding for the past four years at this 

 station. Approximately 700 seedlings were produced. We have 

 about 70 varieties of sweet potatoes known by Hawaiian names 

 and with the exception of a few they bloom" profusely from 

 November to April. Under Hawaiian conditions we find that 

 the sweet potato seeds very freely with the exception of a few 

 varieties which develop seed pods only after they have been 

 artificially pollinated. We also find some varieties non-bloom-
