. The Bulletin of the North Carolina Department of Agriculture. Agriculture -- North Carolina. The Bulletix. 9 recognized by the average farmer until the trees begin to die, and by that time much injury has already been done. It is, therefore, very important to know what the insect is like, and where to look for it, so that the grower may be enabled to detect it before it has already become destructive. Trees thai are very badly infested with the San Jose Scale appear as if the branches had been dusted with ashes, having a grayisli^ scurfy appearance. If these branches and twigs be scraped with a knife it will be found that this unnatural covering is quite easily removed, coming off in little flaky patches. The appearance of a portion of such a branch is sho^Am in Fig. 2, as it appears to the naked eye. (We regTct that this illustration is not clearer, but it is very •difficult to get a satisfactory illustration of this kind.) Examined under a magnifying-glass a thickly-infested twig (during the season when the insects are breeding) will likely present the appear- ance shown at b in Fig, 3. Each of the circular gray objects is a separate scale, each covering a tiny yellow insect ^!.
