 serious, Coccus hesperiduni and the Aleurodes being the most numerous. 

 During the entire year no brown-tail nests or gipsy moth egg-masses 

 were noted.

 Thunb., in Algeria by Coccobacillus acridiorum, d'Herelle.] —

During the past two years, the action of d'Herelle's Coccobacillus 

 acridiorum on Dociostaurus maroccanus, the only economically trouble- 

 some locust in Algeria of recent years, has been studied [see this Review, 

 Ser. A, ii, p. 681]. The power of the virus may be increased until it 

 proves regularly fatal 3-4 hours after inoculation, the infection being 

 chiefly spread by the ingestion of plants soiled by infected excreta. 

 In Algeria, this locust is protected by conditions which are unfavour- 

 able to the disease, because the locusts develop in arid regions where 

 the sparse vegetation does not lend itself to poisoning and only a 

 small proportion of the insects exhibit cannibalistic tendencies. This 

 method of control is, however, a useful accessory to the mechanical 

 methods now in use, particularly in sparsely populated districts where 

 the latter cannot well be employed.

It has been suggested that newly planted young vines could be 

 protected against the larvae of chafers by planting beets or potatoes 

 between the rows as baits. This practice has often been adopted in 

 the Beaujolais-Maconnais district. To conserve the attractiveness 

 of the bait, stable manure must not be used, but only chemical fer- 

 tilisers. Injury may be completed before the potatoes attain to a 

 suitable size, and in such cases lettuces provide a good substitute. 

 In the suggestion originally put forward, the potatoes were old ones 

 of the preceding crop and would, of course, be immediately attractive. 

 The baits must be easily accessible to the grubs, and this is only possible 

 in loose soils.

This book, edited by V. E. Eudev, contains in a popular form, 

 various information on the cultivation of orchards. Harmful insects 

 are also dealt with and the usual remedies against Anthonomus 

 "pomorum, Cydia pomonella, aphids, Psylki, and other pests are given.
