Pteronvs rihesii appears in April or May ; the eggs are laid on the 

 inider side of the leaf near the largest veins. A light dressing of 

 well-seasoned gas-hme over the surface of the soil in early spring is 

 a good preventive. When the larvae are detected on the bushes, 

 hand-picking, shaking them on to waterproof sheets laid beneath the 

 bushes, or spraying with hot water should be resorted to. Syringing 

 with poisonous insecticides is not recommended when fruits are 

 present ; a mixture consisting of 3 gals, warm water, \ lb. soft soap 

 and the same quantity of soot may be safely sprayed on to the bushes 

 on a dull day. The bushes should be syringed about an hour later 

 with clean water.

During the year the cultivation of the bagworm fungus has been 

 carried on, and over a thousand cultures were distributed among the 

 wattle-growers in Natal. The results, however, have not been 

 satisfactory, owing to the dry season. It has been observed that 

 bagworms infesting plantations have been decimated by an infection 

 which is supposed to be bacterial, though several bacteria isolated from 

 dead worms have not proved pathogenic to healthy ones.

The work of the Division has included the suppression of locusts, 

 inspection of nurseries and of plant and fruit imports, and restrictions 

 on the conveyance of fruit and plants. The chief pests found in vine 

 nurseries were Heterodera (root gallworm). Phylloxera and red' scale. 

 Aspidiotus perniciosus was found in one nursery in Pretoria . Quarantaie 

 was imposed on 31 nurseries on account of the presence of Chrysom- 

 phalvs aurantii, C. aonidmn, C. rossi, Lep)idosapihes hechii, Eriosoma 

 {Schzoneura) lanigeruyn and Eriococcus araucariae. Trioza sp., Ap)his
