CRANBERRY DISEASES ON THE PACIFIC COAST

over all the vines. Apparently, commercial dusting of cranberries 
will not prove satisfactory on the Pacific coast until some superior 
method of applying the dust is developed.

COLD-STORAGE EXPERIMENTS 
The question has been raised among the growers as to whether 
cold storage of the fruit might not be substituted for spraying in the 
control of storage rots. The plan was proposed on the following 
grounds: No decay is found when cranberries are picked. If the 
entire crop is screened and shipped immediately, the grower will 
suffer no warehouse loss in the first place. Pacific coast berries at 
present are consumed in an area lying wholly within a radius of three 
or four days' haul from the bogs, and very little rot should be expected 
to develop in a shipment of such short duration so early in the season. 
Consequently the berries would reach the distributing markets in per- 
fect condition very soon after being harvested. They could be imme- 
diately placed in cold storage and held until a market demand arose 
and would then be consumed before any rots developed, if such stor- 
age was found to be satisfactory. Furthermore, it might be possible 
to prolong the marketing season of cranberries by holding them in 
cold storage for later distribution. 
The following data were obtained on cold storage: In 1922 a box 
of Howes berries from the Wilis bog at Long Beach, Wash., was ship- 
ped to Washington, D. C. On arrival two samples of sound berries, 
consisting of about 1 peck each, were sorted out and put in ventilated 
boxes, one of which was placed in the cold-storage plant at the Arling-
