times I have seen fields out in full bloom just like so many 

 morning glories. 



"If you can keep your greenhouse at from 60 to 90 degrees 

 Fahrenheit you can get good plants of the following varieties: 

 Nancy Hall, Golden Beauty, Dooley Yam, White Yam and 

 Porto Rico. All these above-named varieties will bloom if 

 given the proper attention, being careful to keep your green- 

 house at not less than 90 degrees during the day and not less than 

 60 degrees at night. These plants will have to be left in pots 

 for about six months to get the blooms. We get blooms from 

 plants planted in April and left in the field until October. "^ — -J. C. 

 J^ C. Price, Professor of Horticulture, Mississippi Agricultural 

 Experiment Station. 



Texas. "I have had farmers tell me repeatedly that they 

 / had seen sweet potatoes blooming and, in some cases, producing 



seed, but I must admit that during the six years in which I have 

 been connected with this institution in Texas, I have not noticed 

 one single instance of either blooming or seed production of the 

 sweet potato, and I have examined many a sweet potato field." 

 — J. J. Tajbenhaus, Chief, Division of Plant Pathology and 

 Physiology^ Texas Agricultural Experiment Station. 



Louisiana. "Sweet potatoes rarely ever bloom with us and 

 I have no knowledge of any seed ha\-ing been produced in this 

 state. "^ — ^M. Hull, Sweet Potato Specialist, Louisiana Agri- 

 cultural College.

 Department of Horticulture, New Mexico College of Agri- 

 culture.

y^ potato country; the acreage is increasing e\"cry year. On only

(i) "Dr. ICvans of the States Relations Service bought and 

 gave me a number of seed pods of two \arieties of sweet potatoes, 

 the seed of which had been sent from one of the Virgin Islands. 

 This is the first sweet potato seed that has been brought to my 

 attention. We have, however, flowered sweet potatoes a number 

 of times, both in the field and in the greenhouse here in Wash-
