The next se ason they encase them- selves in a saw-dust-like cocoon, in their holes under the bark; and Fis- 2at emerging in the perfect insect, lay their eggs and perish. The perfect insect is very rarely seen, but is easily obtained by enclosing the pupa, fig. 234, b, c, which is readily obtained in summer at the roots of neglected trees, beneath a glass, or in a gauze case. As this insect confines itself to the bark, its destruction is very easy. It rarely happens that trees are completely de- stroyed by it, except they be small; death can only take place when the tree is girdled. Timely care will prevent this ; the evil in fact is only to be dreaded by negligent cultivators. The disease termed the yellows is truly formidable. It is peculiar to the peach and nectarine. It has destroyed whole orchards in portions of the country, and for a time induced the entire abandonment of the peach culture in certain lo- calities. The cause of this malady has not been satisfactorily as- certained. According to conjecture, it has arisen originally from exhaustion by deteriorated soil, overbearing, and neg- lected pruning and bad cultivation. But whatever may have been its origin, it appears at present to be chiefly commu- nicated from diseased trees. It is quickly induced by in- serting the bud from an affected tree into a healthy stock. It spreads by contact with diseased roots ; a knife used in pruning the tree will infuse the poison if used on another. It appears to be communicated without actual contact, the healthy branches nearest a diseased tree being usually first att
