compared with other States, and the cultural methods that are the only 

 known means of control in infested fields. The effects of boll- weevil 

 infestation are discussed, with its bearing upon cotton production, 

 oil mills, ginneries, etc., as well as upon labour and land values, together 

 with the changes in agricultural methods which the presence of the 

 weevil entails. The importance of hastening the growth of plants so 

 as to insm'e a large crop of bolls by the middle of July is emphasised, 

 and simple directions are given for following scientific methods of 

 cultivation which will represent a good investment while no weevils 

 are present and will check their numbers when they do become 

 introduced. The report closes with general observations, suggestions 

 and recommendations to be followed in preparation for boll weevil 

 conditions.

In this brief account of the life and works of Dr. I. P. Trimble 

 (born 1804 — died 1890) mention is made of his " Treatise on Insect 

 Enemies of Fruits and Fruit Trees " published in 1865, a work of 

 139 quarto pages dealing with the plum curculio [Conotrachelus nenuphar] 

 •and codUng moth [Cydia ponwnello]. In 1866 the New Jersey Agri- 

 cultural Society received a grant of £600 for preparing and publishing 

 this work, none of which went to the author, but which was used by 

 the society in publishing and purchasing copies of the book for 

 distribution. The article concludes with a hst of nine entomological 

 papers published by Dr. Trimble between the years 1864 and 1870.

During the month of November the insectary handled 29,400 pupae 

 ■of the melon fly [Dacus cucurbitae] from which 1378 individuals of 

 Opius fietcheri were bred and distributed. The following parasites 

 were also distributed : — Tetrastichus, 700 ; Diachasma fidlawayi, 110 ; 

 D. tryoni, 665 ; Paranagrus (corn leaf-hopper parasite), 13,500.

This paper contains the official report of a locust invasion that 

 occurred in Chile in January 1917. The species concerned was 

 Schistocerca paratiensis, Burm. (Argentine locust) which has on 

 previous occasions invaded the south of Chile. Apparently no serious 

 •damage was done to agriculture and no complaints of losses have 

 been made. Writing before the end of the invasion the author con- 

 •siders that in view of the season in which the swarm appeared, the 

 unfavourable climatic conditions for acclimatisation of the locust on 

 that side of the Andes, and considering the history of previous invasions, 

 it is unlikely that locusts hatching from the eggs laid will ever develop 

 into hoppers.
