R. S., San Jose, under the date of August 8th, writes: - "Our fruit trees here are now infested with what they call the " Red Scale Insect." It has destroyed thousands of trees. Concentrated lye has been used with some success - quantity one to five of water. The insect discolors the bark underneath to a purplish red hue, found upon scraping the infected parts. Rumor says it has been brought here in orange boxes, and that it is quite common in Sicily; be that as it may, there is quite a scare about it, and many fear the total destruction of their trees. Meetings have been held for discussion as to the best mode of getting rid of him; cannot you give us a point? I think your article on " Scale on Orchard Trees," in this month's number would do the business. Those who have fought him have done so in the winter after leaves are all gone, and the insect, to my way of thinking, impervious and dormantly secure in his scale. Would it not be better to fight him in the spring at or about the time he is hatched out and leaves the scale to make new locations and found new colonies? It seems to me this is the best time for its destruction.
The task is a gigantic one, as in some orchards not a tree but what is infested.
