Other. This must be clue to a differeuce between the internal conditions of the 

 plants at different developmental stages." 



As a test of the methods employed the results indicated that many of the new 

 methods proposed for work of this kind " are of value, and the data obtained 

 by their means throw light upon the question of the influence and relative im- 

 portance of several different climatic features, as these affected the growth of 

 the culture plants." They indicated that culture plants may be successfully 

 used as integrating instruments for the measurement of climate, that the 

 autoirrigator furnishes a satisfactory means for soil moisture control, and that 

 the standardized cylindrical porous-cup atmometer, taken with the ordinary pre- 

 cipitation records, gives a ratio of rainfall to evaporation that appears to be a 

 very valuable measure of moisture conditions. Sunshine records obtained by 

 the Marvin sunshine recorder were also found to be of some value. 



Weather forecasting-, G. S. Bliss (U. S. Dept. Agr., Weather Bur. Bui. ^2, 

 2. ed. {1911), pp. SI, figs. ^).— In this second edition (E. S. R., 29, p. 120), " the 

 style and subject matter have been alternated slightly to conform more closely 

 to the uses to which the pamphlet has been put. The errors that crept into 

 the first edition have been eliminated so far as possible, thus bringing it up to 

 date and in accordance with our present knowledge of the subject." 



Weather observations, A. J. Fakley (Neio Jersey Stas. Rpt. 1915, pp. 65, 

 66). — Observations on temperature and precipitation at New Brunswick during 

 1915 are summarized. The maximum temperature, 92° F., was recorded July 

 31 ; the minimum, 2°, December 27. The total annual rainfall was 50.03 in., 

 1.31 in. above the normal. 



[British rainfall in 1916], H. R. Mill (Times [Londmi], 1917, Jan. 25; rev. 

 in Nature [London], 98 {1911), No. 2466, p. 435). — Detailed results are given 

 for 131 stations. These show that 1916 was generally a wet year in the British 

 Isles, the rainfall being far in excesa of the average at most stations and 

 slightly below at a few. A deficiency of rainfall occurred in the extreme 

 southwest of Wales and the northwest of Devon and Cornwall, and in two 

 areas in the center of England. The area over which the year was relatively 

 dry was much less than in any other of the last 12 years except 1912. 



" The excess of rain was most pronounced in the south of England, the center 

 of Scotland, and the southwest, northwest, and east of Ireland. The wettest 

 part of England was in the district of East Grinstead, where the excess was 

 about 40 per cent. In Scotland the excess of rainfall was 20 per cent over 

 nearly one-half of the country, while in parts there was an excess of more 

 than 40 per cent. The whole of Ireland was wet ; the greatest excess of more 

 than 30 per cent stretched inland from Dublin Bay. No year since 1903 has 

 been wetter than last year in Scotland and Ireland, while the British Isles 

 as a whole have only been wetter than 1916, during the last 50 years, In 1903, 

 1882, 1877, and 1872." 



Results of rainfall observations in New South Wales, 1909-1914, H. A. 

 Hunt et al. {Melhourne: Govt., 1916, pp. 224, pis. 14, fig. 1). — This is a con- 

 tinuation of a report published in 1909 bringing the rainfall history of New 

 South Wales up to the end of 1914. 



"The work, in addition to the general notes, includes tabular statements of 

 rainfall at some 2,100 stations for the years 1909 to 1914, inclusive, and the 

 annual averages computed from the commencement of the period over which 

 the records extend ; also rainfall notes and maps for each of the foregoing 

 years; a statement and graphs showing the state of the rivers since the last 

 report; a very carefully prepared table showing the yearly rainfall averages 

 derived from selected stations in each of the divisions of the State, also the
