Soil temperature observations at the observatory of Catania, 1892-1896. 

 E. Trixcai.i (Alii dcoad. Gioenia Sci. Nat.; abs. in Nature, 58 {1898), No. 1489, p. 40). — 

 "In addition to confirming the well-known laws according to which the diurnal and 

 annua! variations of temperature decrease and undergo retardation with increasing 

 depth," tlic results of these observations "show that at Catania the velocity of 

 transmission of the diurnal fluctuations is about 20 cm. for every 74 hours, and that 

 those fluctuations become practically unimportant at a depth of 60 cm., where they 

 only amount to a lew tenths of a degree when the atmospheric temperature changes 

 as much as 17 degrees."

FERTILIZERS. 



The fertilizer industry, J. Hyde and G. K. Holmes ( U. S. Bept, 

 Ayr., Division of Statistics Bui. 13, pp. 27). — This bulletin contains 

 statistics of production aud consumption of fertilizers in the United 

 States; a preliminary report on a statistical study of the relation 

 between the fertilizers applied and the profit obtained in cotton grow- 

 ing: and notes on fertilizer inspection, with abstracts of the different 

 State fertilizer laws and a list of fertilizer inspection officials. 



It is estimated that the total number of establishments in the United 

 States that manufacture fertilizers is about 700. In 1880 the census 

 reported 364 ; in 1890, 3 ( J0. " Since 1890 there has been a very consider- 

 able development in the manufacture of fertilizers, especially in South 

 Carolina and Florida, where phosphate mining has assumed large 

 proportions." 



It is stated that attempts to collect statistics of the production of 

 fertilizers have been unsuccessful. ''With respect to consumption, 

 however, the case is different, and it has been possible, with the aid of 

 State fertilizer inspectors and other State officials, to ascertain approx- 

 imately the quantity and value of the commercial fertilizers consumed 

 in the United States in the calendar year 1896." More or less complete 

 data are also given for the period from 1891-1895, aud for the first 

 nine months of 1897.
