Gooi/'s whaU oil soap no. 3, i^ pounds to the gallon. Seven trees 

 were treated with this strength of the insecticide on the same day and 

 under the same conditions as in the preceding experiments. Their con- 

 dition at the beginning of the test was as follows. Tree 29, a globe 

 peach 6 feet high, was badly infested with San Jos^ scale. Trees 30 and 

 31, the same kind and 10 feet high, were infested with but few scales, 

 while tree 32, 14 feet high, was moderately infested. Trees 108 and 109, 

 Hartleti and beurre bosc pear 7 and 10 feet high respectively, were 

 moderately infested, and tree no, a Kieffer 10 feet high, was rather 

 badly infested.

 treated with this solution. Their condition at the beginning of the ex- 

 periment was as follows: tree 69, a Howell pear 9 feet high , tree 70, a 

 Clapp's favorite 12 feet high, and tree 71, a Flemish beauty 6 feet high, 

 were all very badly infested with the San Jose scale. Tree 86, a Craw- 

 ford peach 10 feet high, was moderately infested with the scale. Tree 

 87, an old Mixon 12 feet high, was very badly infested, and tree 88, 

 same kind and size as the preceding, was badly infested with the scale.
