eceruleoeephala). The caterpillars make their appearance in the spring, and at 

 once commence their devastations. They are about two inches long when fall 

 grown, of a yellowish green colour, and have a bluish head, and one dorsal and two 

 lateral pale yellow stripes. In June they form a case of moss or chips of wood, on 

 the trees, or in the crevices of adjoining walls, and change into the pupa state. 

 The moths appear in October and November, and soon afterwards deposit their eggs 

 on the trees. The removal of the caterpillars by hand picking is the only known 

 remedy that is at all effectual in the destruction of this pest. The caterpillar of the 

 small Ermine Apple Moth, Yponomenta malivorella, also sometimes do considerable 

 mischief. They devour the leaves in spring and the early part of the summer, and 

 at the same time cover the shoots and branches with thick webs. In these they 

 spin a cocoon, and change into the chrysalis state. About the end of June a white 

 moth appears. The only remedy is to catch and destroy the moth and the cater- 

 pillars. As the caterpillars are rather sluggish during the day, it has been recom- 

 mended to lay a sheet underneath the trees, and tap the branches sharply with a 

 stick, to shake them on to the sheet, when there will be no difficulty in destroying 

 them. Later in the season, apple-trees which have escaped the attacks of the 

 enemies described above, sometimes suffer from the caterpillars of the Brown Moth 

 {Clisiocampa Americana). These are hatched towards the end of May, and for 

 six or seven weeks they feed upon the leaves, sometimes completely stripping the 

 trees. The only known remedy is hand picking, which is both tedious and unplea. 

 sant. If the trees are badly infested, numbers may be frequently shaken off the 

 trees, and when on the ground, destroyed. As the caterpillars of so many moths 

 feed upon the leaves of the apple-tree, we cannot do more than direct your atten- 

 tion to them, and give a brief descriptioa to assist you in their identification, and 

 point to the most practicable remedies. 



Salted Lawn. — W., East Yorkshire. — You can do nothing but wait for the 

 rains, which will encourage the grasses that have not been injured by the action 

 of the salt to make a vigorous growth, and obviate the brown patches. The lawn 

 will be more or less unsightly until the autumn, when the turf will again present 

 a uniform appearance. The query was not received in time for answer in the June 

 number ; and we cannot undertake to answer queries through the post, however 

 desirous we may be to assist onr readers in their difficulties.
