Prof. McAdie of the United States Weather Bureau, who has been studying the frost problem, says : "The growers are now pretty well able to protect the orange trees from , but iiow to save the almond crop is a serious and very important question. The frost renders tlu" almond crop about the most uncer- tain we have. 1 have made arrange- ments at several places to have a few- almond trees set apart for special and experimental treatment during the frost season. These trees will be under my supervision and we will see what results can be achieved. One metliod of Treat- ment will be to turn the hose on them. The water will freeze and the trees will be encased in ice. The scientific reason for the treatment is that tlie damage conies from the sudden warming up of of the tree after being ehilled. The coat ing of ice will prevent ; Prof. IMcAdie's experiment in this di- rection will undoubtedly prove a .success. His a well known fact that if tender plants in the garden are frosted during a cold night, they may be saved by sprinkling them with cold water before the sun rises, and there is no reason why the same remedy should not apply in the case of frosted trees. But there is another xiew of the matter. Trees will run about 108 to the acre. Frost fighting must be done between 4 and 8 o'clock in the morning, giving about four hours working time. It will take an ordinary man about ten minutes to spray the aver- age tree, so that in four working liours he could treat twenty-four trees, or say four men to the acre, so that a hundred acre orchardâand this is not a large or- chard by any meansâwouM require 400 men witn 400 spray pumps to fight frost by the method suggested by I\Ir. McAdie. Now, we don't know a single Imndred acre orchard in California where they keep 400 men who would be willing to turn out at 4
