PEACH AND THE PEAR. 297 



Stock or perforates it in every part, and, if not destroyed, 

 finally causes the death of the tree. Pick it out with a 

 knife, or poke it to death with a wire. Pile ashes around 

 the trunk and it can't reach the quince to deposit its

 the orchard in June nights, and thousands of these and 

 other beetles will be destroyed. These fires are to be 

 recommended in all Peninsula fruit orchards, in the warm 

 nights of May and June, yearly.

 side of body copper colored, and covered with whitish 

 wool. Its legs are yellow and green. Its larvae are un- 

 known. Destroy them by night-fires in the orchard. 



The seventeen year locusts — Cicada Septendccini — 

 may destroy Pear trees. The larvae, in countless numbers, 

 are sometimes found at the roots of declining trees, with 

 their suckers piercing the bark. Dig them out and apply

Another enemy to the pear is described by Harris 

 as the Pear Tree Psylla — Psylla Pyri — Harris' descrip- 

 tion is taken from KoUar's Treatise. The Psylla comes 

 from its winter retreat provided with wings, as soon as
