Fruit-growing 275 



6. The peach-tree borer. During the month of May visit a near- 

 by peach orchard and look for borers. Dig the earth away from the 

 base of the tree to a depth of six to eight inches and, whenever a borer 

 is found, either cut into the burrow with the knife, find the borer, and 

 kill it, or push the piece of wire through the burrow until it strikes the 

 borer and kills it. When using the knife destroy as little bark as 

 possible. Make the cut up and down, not around the tree, to avoid 

 girdling it. When finished with the work place the soil back about the 

 tree to prevent the roots from drying. Visit the orchard again in 

 September or October and kill what borers you find. 



7. Decay in fruit. Bruise two apples by striking them on the top 

 of a table. Do not break the skin. Bruise two others by striking them 

 against a sharp corner of the table. Let the skin be broken slightly. 

 Keep the other two as a check. Place all the apples where they will be 

 undisturbed and watch the results. Keep a record of the length of 

 time that occurs before each shows decay.
