small numbers ; in a second, large numbers occurred on neighbouring 

 elms ; and in a third, the total destruction of the insect was prevented 

 by the presence of long grass in which the stupified insects recovered 

 and survived. It is therefore recommended that : — An orchard be 

 fumigated in addition along its edges, especially if it is surrounded by 

 trees ; each fumigating heap should contain not less than 5 lb. of 

 tobacco dust and 10 lb. of straw, the lines of heaps being not more 

 than about 23 yards apart ; they must be carefully watched and 

 stirred until completely consumed ; the grass in the orchard should 

 be cut as early as possible.

Eriocamjtoides aethiops, F., attacks the leaves of roses from the end 

 of May till the first half of July. The larvae remain in a cocoon in 

 the soil during the latter part of the summer, the autumn and winter, 

 pupating early in spring and producing the imago in May. The 

 remedies are : spraying with arsenate of lead or calcium arsenite in 

 May, and the cultivation of the soil beneath the bushes in autumn or 

 early in spring.

A short account of the life-history of scale-insects is given, with 

 some remedies against them. In orchards the best results are ob- 

 tained by spraying with a mixture of lime, crude carbolic acid and 

 iron sulphate ; in nurseries the same spray may be used, but somewhat 

 weaker, viz :— 1 lb. of iron sulphate, 4 lb. of freshly slaked lime, a 

 quarter of a pint of carbolic acid and the same quantity of molasses 

 in 3 gallons of water. The spray must be repeated early in spring 

 before the unfolding of the buds. Hot-houses may be disinfected 

 with a solution containing 3-5 lb. of iron sulphate and a quarter of a 

 pint of carbolic acid in 3 gallons of water.

The control of Phlyctaenodes sticticalis in market gardens comprises : 

 (1) spraying the attacked plants with barium chloride, Paris green, lead 

 arsenate, or calcium arsenite ; (2) handpicking, if the number of the 

 caterpillars is not great ; (3) spraying the caterpillars themselves mth 

 kerosene or carbolic emulsion ; (4) cultivation of the soil in autumn 

 and early spring to destroy the caterpillars wintering in cocoons.
