 Summary of meteorological observations (p. 38). 



Summary for four years — October, 1884 fo October, 1888. 



Preservation of the sweet potato in winter, W. L. Jones, 

 M. D. (pp. 39-42). — A record of one year's experience with sweet pota- 

 toes kept in a pit and in a dry well. 



Tbis experiment is published, not because it furnishes a basis for deduction, but to 

 direct attention to this very important matter. If it was known exactly under what 

 conditions sweet potatoes could be preserved through the winter, their cultivation 

 would increase largely, for they are easily raised and can be converted into very 

 cheap pork, milk, and butter. 



BULLETIN NO. 3, APRIL, 1889. 



Entomology, J. P. Campbell, Ph. D. (pp. 45-49). — Compiled notes 

 on the melon worm [Eudioptis hyalinata, L.), pickle worm {Eudioptis niti- 

 dalis, Cram.), and harlequin cabbage-bug [Strachia histrionica, Halm). 



Additional ash analyses of native woods, H. C. White, Ph. D. 

 (pp. 50-53.) — A continuation of the work recorded in Bulletin 'No. 2, 

 (pp. 17-26). The woods examined were long-ieaved pine {Pinus palus- 

 tris) and magnolia {Mayjiolia grandiflora). 



Cow-pea as a fertilizing crop — Manures for, W. L. Jones, 

 M. D. (pp. 54-58). — A record of experiments with fertilizers on cow- 

 peas. "The pea responded promptly to mineral manures." 



Preservation of the sweet potato in winter, W. L. Jones, 

 M. D. (pp. 59-61). — A record of the continuation of experiments reported 

 in Bulletin No. 2 (pp. 39-42). 



One or two conclusions only can be drawn at present; one is that sweet potatoes 

 may be kept through the winter when the temperature to which they are exi^osed is 

 within the limits of 38.1° and 88<^ Fah., and the average about 52°; another is that a 

 damp atmosphere is not prejudicial to their keeping, neither is the presence of dif- 

 fused daylight.
