a constant trouble, both in gardens and Hop grounds. 

 It spins a fine web over the leaves or other parts of 

 the plant it attacks, and amongst these threads it 

 fastens its eggs, and under their shelter the young 

 Eed Spiders are protected. 



The worst attacks of these Mites take place in dry 

 seasons ; and one desirable remedy is considered to be 

 washing the infested plants with soft-soap, applied by

means of field washing engines, or lesser power, as 

 may be requisite. 



During winter the Eed Spider shelters in crannies, 

 under stones or clods, in cracks in Hop-poles, or, in 

 fact, in any convenient nook ; and where it is present 

 to a very injurious extent on wall trees, I have found 

 that rubbing the bark thoroughly with soft-soap, or 

 applying a mixture of gas-lime and soft-soap 

 thoroughly, but not roughly, rubbed on by hand, 

 did great good. A good dressing of gas-lime was also 

 laid in a line at the bottom of the wall to keep the 

 Mite from crawling up, and thus the trees were 

 cured. Sufficient moisture to ensure a vigorous 

 growth appears an important means of prevention of 

 attack.
