Drought, drainage, and subirrigation, W. Clatworthy {Queensland Agr. 

 Jour., 13 {1903), Xu. 2, pp. 133-137). — A brief Jiccount of experiments in which 

 there was used "for the purpose of subirrigation and drainage combined a 2-in. per- 

 colating, porous pipe made in 18-in. lengths, which served admirably the double 

 purjiose of irrigatif)n and drainage for small areas. . . . The number of pipes per 

 acre, laid 15 ft. apart, was about 2,000, the cost of which was 10s. per 100 ft. at the 

 factory, making the total cost for pipes alone £15 ($75) per acre." 



The value of water power, L. Koch {Filhling's Landw. Ztg., 52 {1903), No. 19y 

 pp. 712-715). — A l)rief discussion of the relative cost of steam and water power. 



Roller gins for cotton, F. Main .(Jour. Agr. Prat., n. ser., 6 {1903), No. 40, ]>p. 

 443-447, Jigs. 5) . — Several impjroved roller gins are descriVjed. 



Time and cost of making earthworks, M. Ringki.mann {Joxir. Agr. Prat., n. 

 ser., 6 {1903), No. 40, pp. 447-450). — Simple methods of making estimates of these 

 factors based on an examination of the character of the soil. 



On the reduction of nitrates by sewage, Letts, R. F. Blake, and J. S. Totton 

 {C'hcm. Neii:<<, ,9S {1903), No. 2289, ]>j>. 16'2, 1S3). — A brief account is given of a study 

 of this subject with reference to the ])acterial purification of sewage. 



The misuse of physics by biologists and engineers, W. S. Franklin {Science, 

 n. ser., IS {1903), No. 464, pp- 641-657, Jigs. 2). — In this paper the author argues that 

 there is a sharp line of demarcation "between systematic physics and what we may 

 call statistical physics . . . suggesting in a general way the error of the indiscrimi- 

 nate application of the philo.sophy of the exact sciences in the study of natural phe- 

 nomena. ' ' The author' s position in brief is ' ' that the idea of quantitative relationships 

 and the idea of one-to-one correspondence in general, as these ideas are known in 

 physics, are inapplicable and necessarily fruitless in sucli fields as physical psychology 

 and meteorology."
