A larger variety of thrips generally affects Rose blooms in the open, more especially when the summer has been very dry. These completely spoil the light-coloured flowers. There seems no way of getting rid of these, and it is fortunate that the first shower is the best remedy. Syringing has been resorted to in hopes of accomplishing the same end, but never with any material benefit. Scale is a small shell-covered, brown insect, ranging in size from a small to a large pin's head. It is difficult to kill, and unless the plant be of much value, it is best to burn it at once. Climbing Roses under glass are most affected by this pest. Caterpillars and grubs must be killed by hand ; so too must the leaf-curling maggots. No syringing seems to actu- ally kill these without being too strong for the Rose itself. Pinch the curled leaf and insect between the thumb and finger. A little observa- tion soon makes it easy to distinguish between those curled by the enemy, or naturally curled before full expansion, and perseverance for a few days early in the season will keep them at bay for the rest of the sum mer. Weevils are a great nuisance during some seasons, especially the night feeders. They eat holes in both petals and leaves, and also gnaw around the pod of the bud to such an extent as to quite spoil it. Here, again, the best method is hand catching. Approach the plant very WK^,^^mm^^mPs^.^\^kT« quietly late in the evening, slip a sheet of paper below it, and then flash a light on it, the result being that many may be caught before they can drop and regain their shelter. Amongst the worst and early summer pests are the stem-boring saw-flies and their larva?. These lay their eggs in the points of shoots, and the maggot soon hatches, eats the pith out of the stem, and causes it to die above. Ma
