Some clim^atic features of the Territory of Hawaii, W. H. Stockman {Hono- 

 lulu Chamber Com. Ann., 1908, pp. y0-9.'t). — Data regarding temperature and 

 rainfall are summarized, attention being called especially to the great diversity 

 of climatic conditions in the Territory. These vary " from the eternal spring 

 obtaining at sea level to the invigorating, ideal temperatures experienced at 

 altitudes ranging from about 500 to 2,500 ft. on all the islands, and the freezing 

 weather which obtains on the u()per slopes of JNlount HaleaJ^ala on Maul, and 

 Mt. Mauna Loa and Mt. Mauna Kea on Hawaii ; and from the torrential rains 

 and moist atmosjjhere of the higher levels on the windward sides of all the 

 islands to the light rainfalls and small percentage of relative humidity on the 

 leeward sides. 



" The topography and altitude of a place or district of these islands has a 

 decided effect on its climatic conditions, but the controlling factor — other than 

 latitude — is, perhaps, the directness with which the warm, moisture-laden trade 

 winds pass over it, for any obstacle that deflects from their true course these 

 winds — which here blow with great steadiness and considerable force — has a 

 marked effect on the rainfall, and a modifying one on the temperature and 

 Inunidity conditions."

 i'j9). — This report is divided into 3 parts: (1) Daily observations at IS sta- 

 tions of the second order, (2) monthly and annual sunuimrles of all the meteor-

British rainfall, 1907, H. R. Mill {London, 1908, pp. 100+280, pis. 5, figs. 

 25; rev. in Nature [I.ondon], 78 {1908), No. 2033, p. 6C//).— This report is in the 

 usual form and "deals with the distribution of I'ain in space and time over 

 the British Isles during the year 1907, as recorded by ujore than 4.000 voluntary 

 observers, and is supplemented by articles upon various branches relating to that 

 subject." 



Among the special articles are a discussion of the typical thunderstorms of 

 July 21-22, " showing distinctly the linear arrangement of heavy rainfall in 

 such storms and its disregard of the configuration of the land," and a note on 

 mapj)ing rainfalls (E. S. li., 20, p. 213). There are also discussions of droughts 

 and rain spells.
