EXPLANATION. — Whenever an asterisk (*) is used it cautions against spraying with poisons while the plants are in blossom ; a dagger (t) indicates 

 ihat. there is danger of making an application within three weeks of the time the fruit is to be used as food. While tne numoer of applications recom- 

 mended will be found desirable in seasons when the fungi are particularly troublesome, a smaller number may often suffice.
