 and preventing the plant carrying on its proper functions. 

 There are two broods in a year. 



Eembuies. — Spraying the fohage tlioroughly with Caustic 

 AlkaU Washes (Nos. 1 or 8) in winter. All infested 

 prunings should be promptly burnt. Dusting quicklime 

 among the branches in winter, while moist, will likewise 

 help to destroy these pests. See also remedies advised 

 for Mussel Scale, on p. 71. 



Gooseberry Red Spider (Bryobia ribis).— This 

 is a small mite, or form of red spider, which in very hot 

 and dry seasons infests the leaves of the gooseberry to a 

 very serious extent. Like the ordinary Red Spider of the 

 garden and greenhouse, it dislikes moisture and cold; con- 

 sequently, as already intimated, it is not likely to be very 

 numerous or destructive, except in dry, hot seasorus. The 

 mite can hardly be seen individually by the naked eye, 

 but its presence may be easily detected on the foliage of 

 the gooseberry by the pale colour, and by the fact of the 

 surface being dotted with minute reddish spots, covered 

 by a very thin silken web. On examining the foliage with 

 a magnifying glass the web will be clearly seen, and 

 underneath it the colony of mites. These mites puncture 

 the epidermis of the leaf and extract the sap. They in- 

 crease very rapidly; so much so that hundreds and thou- 

 sands may be found upon a single leaf. 



Kembdies. — Directly these pests are found infesting 

 the leaves of the gooseberry the trees should at once be 

 sprayed with a Kerosene Emulsion (No. 16). One spray- 

 ing may not be sufficient, so repeat the operation until 

 all traces of the pest have disappeared. 



Gooseberry Sawfly (Nematus ribesii). — Though 

 called the Gooseberry Sawfly this pest is also very partial 

 to the fohage of the red currant. The perfect insect ap- 

 pears late in April or early in May. It measures about 

 one-third of an inch in length, has a dark-coloured head
