(Stumus vulgaris), which attacks the mature fruit, but even this 

 bird has a beneficial effect on the vines at any other season. These 

 beneficial birds should be protected whenever possible from predaceous 

 animals, especially as many of them nest on the ground ; in cultivating 

 the vineyards also care should be taken not to destroy the nests. 

 The construction of special shelters for these birds and the planting 

 of suitable trees about the vineyards are the best means of encouraging 

 these most efiicient enemies of vine pests.

An account of the damage to peas in Gironde by the Nematode, 

 Heterodera schachtii, and the subsequent infestation of the plants 

 by the fungus, Fusarium vasinfectum, has previously been described 

 [see this Review, Ser. A, v, p. 471]. As a remedial measure it is 

 suggested that the pea crop should be alternated with one that is 

 not attacked by this Nematode. When peas are infested, the plants 

 should be pulled up immediately after the crop is gathered, and burnt. 

 The ground should then be dug up and dried as much as possible ; 

 if peas or some other susceptible crop, such as beets, oats, turnips, 

 cabbages, must then be grown, they should not be sown until late 

 in January.

The work of the various entomological and pathological stations 

 at Paris, Blois, Bordeaux, Montpellier, Saint-Genis-Laval and Cadillac 

 during 1916 and 1917 is here reviewed, as well as the special investiga- 

 tions undertaken under the direction of the sanitary and scientific 

 services. Almost every station was badly handicapped by shortage 

 of staff owing to the War and by the mobihsation of the directors. 

 In 1917, a new insectarium was estabHshed at Mentone, chiefly on 

 the initiative of the syndicate of olive-growers of Nice and Provence, 

 for the study of remedial measures against the insect pests of southern 

 crops and the acclimatisation of their natural enemies. Colonies of 

 Novius cardinalis were bred as a control for Icerya sp. and the African 

 parasites of Dacus oleae were dealt with, but the season was unfavour- 

 able for rearing Opius concolor. Investigations were undertaken at 

 Cannes for remedial measures against Chrysomphalus dictyospermi on 

 oranges. A mixture of 8 lb. hme and 16 lb. sulphur with sufficient 

 water to make 10 gals, was sprayed on the trees in February-March,
