Scale, and in August for the liose Scale. In cases of 

 a bad attack spray also in winter with a solution of Gis- 

 hurst Compound, 



Weevils — The liaspberry Weevil (Otiorhynchus 

 picipes) and the Red-legged Weevil (Otiorhynchus tene- 

 bricosus) attack the foliage of roses by night. They are 

 also not particular .about eating the flower-buds and young 

 shoots. During the day they hide in crevices of the soil, 

 ascending the stems at night. They are not very large, 

 and of a brownish or black colour, and when disturbed 

 fall to the ground and feign death. 



Remedies. — Lay pieces of sacking on the ground under 

 the bushes; lift these at daylight, and the weevils will be 

 found hiding beneath. Dig in Vaporite or Kilogrub 

 around the bushes to destroy the ova and larvi^e in the 

 soil. 



Other Pests.— Thrips and Red Spider also infest 

 roses grown under glass, the remedies for which will be 

 found in the section devoted to greenhouse plants. 



B DISEASES. 



Anthracnose (GlcBOsporium rosa?, Hals.).— When a 

 rose is badly infested with this fungus the leaves are 

 small and pale, and the shoots die at the tips. Sometimes 

 the stems may be dead for a foot or more from the extre- 

 mity. Not infrequently one branch will be dead clear to 

 the base, and sometimes two or more are thus destroyed. 

 The dead twigs show pimples quite evenly distributed 

 over the surface, and from some a minute, often curved, 

 horn of a reddish colour protrudes. When such stems 

 are placed in a moist chamber the whole decaying surface 

 becomes closely covered with numerous, almost brick- 

 red, masses of spores, and the disease spreads rapidly 

 through the adjoining parts of the twigs that seemed 

 healthy when placed in the moist chamber. The rapidity 

 vvith which the fungus would spread was a subject of sur-
