 bureau. Seed World 7^2 : 13-15. 1920. 



1027. Hood, G. W. Keeping qualities of hubbard squash. Proc. Amer. Soc. Hortic. 

 Sci. 16: 186-188. (1919)-1920. Hubbard squashes were kept in storage from November 1 

 until last of March. The temperature of the storage room fluctuated between 40-50° F. 

 Fourteen average-sized specimens were placed in storage two succeeding years. The aver- 

 age shrinkage, due primarily to water loss, was 23.18 per cent; the greatest monthly shrinkage 

 was in March. — H. A. Jones. 



1028. Hood, G. W. Varietal variations as seen in similar methods of training tomatoes. 

 Proc. Amer. Soc. Hortic. Sci. 16: 183-185 (1919)-1920.— Stone, June Pink, and Earliana varie- 

 ties of tomatoes were handled as follows in the open field: (1) staked and pruned to one stem, 

 (2) staked and not pruned, (3) pruned and not staked, and (4) neither staked nor pruned. 

 All varieties produced the greatest amount of ripe fruit when the vines were neither pruned 

 not staked. The Stone and June Pink produced the least amount of ripe fruit when the 

 vines were both staked and pruned, while the Earliana produced the least amount of 

 ripe fruit when pruned and not staked. In no case did the plants that were neither pruned 

 nor staked produce the maximum amount of green fruit at the end of the season. H. A. 

 Jones.

 tance of keeping the storage sanitary and of maintaining correct temperatures is pointed out.
