Sanford system of irrigation {Queensland Agr. .Jour., IS {WO.i), No. 4, PP- 308, 

 309). — A conil)ined system of subirrigation and drainajje by means of glazed and 

 iinglazed tile, which is claimed to be in successful operation at Sanford, Fla., is 

 l)riefly described. "The field is gridironed with a system of earthenware tile, about 

 18 in. below the surface, in S(iuares of about 20 ft. The pipes running down the 

 incline are of glazed tile, water-tight; these are the conducting pipes. The cross- 

 ]iipes are of unglazed tile, not water-tight; these are used both for drainage and irri- 

 gation." 



Irrigation in Tonkin [Jour. Agr. Trop., 3 (1903), No. 29, p. 349).— A ))rief note 

 on l'\'sch's device used for raising water for irrigation in the uplands of Tonkin,

Irrigation by means of artificial underground water, K. E. Widegren 

 {Agr. Jour. Qxpe Good Hope, 23 {1903), Nos. 4, pp. 456-461; 6, pp. 659-665, figs. 3).— 

 In this article the author discusses the feasibility of storing the water of streams in 

 time of abundance by running them onto lands which present suitable infiltration 

 areas, thus increasing the underground supply, which may be drawn on in time of 

 scarcity, and explains in some detail the jirinciples w'hich underlie the suggested 

 l)lan.

 '23 {1903), No. 5, j)p. 554-557, pi. 1). — The value of a pumping plant in case of a 

 shortage of the usual supplies of irrigation water is explained and 7 designs of such 

 plants a''e l)rietiy described and illustrated.

Device for flood gate and for clearing silt from before intake gate, F. 

 Frank {Agr. Jour. Cajie Good Hoj)e, 23 {1903), No. 5, p. 519, pi. 1). — Drawings and 

 a brief description are given of a gate which automatically closes when a flood 

 reaches a given height, and causes an acceleration of the current past the intake 

 gate so that accumulations of silt are removed.
