284 EXPERIMENT STATION RECORD. [Vol.36 



The type of colon bacillus occurring in surface waters, L. A. Rogees {Ahs. 

 in Jovr. Bact., 1 {1916), No. 1, p. 82; CJieni. Abs., 10 {1916), No. 16, p. 2115).— A 

 collection of 137 cultures of the colon type isolated from waters of greatly vary- 

 ing degrees of contamination was separated into two distinct groups. One of 

 these included about one-third of the cultures and was evidently identical with 

 the type which has been found to include from 95 to 99 per cent of the colon 

 bacilli of bovine and human feces. This type was found occasionally in springs 

 in which there was no evident source of contamination, but was especially 

 abundant in rivers and streams usually considered to be polluted with sewage. 



The second group which occurred in practically all waters examined was 

 identical with a tj'pe which, while it responds to aU of the usual tests for 

 Bacillus coli, occurs in feces in relatively small numbers. Cultures isolated from 

 grains belonged almost exclusively to this type. The significance of this type 

 in water can not be determined, but the characteristic fecal colon type can be 

 demonstrated in polluted water with reasonable certainty. 



Running water possible for every country home, R. U. Blasingame {Ala. 

 Polytech. Inst. Ext. Serv. Circ. 4 {1916), pp. 31, figs. 7). — This circular describes 

 and illustrates five water-supply systems especially adapted to Alabama farm- 

 home conditions and varying in price from $18.50 to $126.14. " Each system 

 has been so designed as to allow the addition of further equipment at any time 

 funds may become available." Bills of material are also included. An arrange- 

 ment whereby the water tank may be placed on a concrete or tile silo is de- 

 scribed. " This practice is becoming rather general in Alabama, and is econom- 

 ical, in that it eliminates the expense of a tower." 



First report of the state engineer of New Mexico, J. A. French {Rpt. State 

 Engin. N. Mex., 1 {1912-1914), pp. 120, pis. 15). — This report covers the period 

 July 12, 1912, to Dec. 1, 1914, and is divided into two main sections. One re-
