 Bulletin, No. 203. The distribution Of waters in the soil fin furrow frriga- ton. By R. II. Loughridge. Ph. D., of the University CT California.
 This bulletin con;a.ns the results of observations upon the pcrcoIation of water in the soil beneath the fur rows in which water is applied to or chards in the vicinity of Riverside. Cal These observations were made as a part of a study of tlte losses of irri- gation water and thea prevention. In the vicinity of Riverside the available water supply has been put to use, and further expansion of the irrigated area depends upon more economical use of this supply. Canals have been lined to prevent seepage losses. the or chards are intensively cultivated to
 check evaporation losses, and thIs
 study was undertaken to arrive ar some knowledge as to the losses by percolation. with view to taking steps to lessen theIL if practicable. It does not. however. go into the dues- tion of methods of checking tacse
 losses. The report contains tine re- suits of observations on a number of orchards. the results showing clearly the great necessity Of each 0rchardist examining his own soil and subsoil conditions and adapting his methods 10 these conditions.
 Bulletin No. 205 Irrigation in Wy. Oning. By C. T. Johnston, state en- | gineer
 The great activity in the construc. l tion of irrigation vzorKs throughout the vest by the government and by private parties has lcd to a heavy de mand on this department for informa- | ton as 10 the opportunities for set. clement on irrigated lands, the crops | grown, the cost of land and water the capital required to establish a
 home, and in general a knowledge of the conditions To be met This bulle tin gives such information for the state of wyoming. It describes the larger irrigation enterprises of the
 state and gives the conditions gov erning the requirement of land and water
 Tho use of small water supplies for | irrigation. By SamL el Fortier. chiei : of irrigation investigations (Scpa- rate from the Yearbook Of the C. S ! department of agriculture for 1907. This article dis'-1zses the possibili. ! ties of securing wafer supplies from i springs, wells. and stored storm va 1 ters, and gives the results of the use
 Of such supplies in typical instances i The methods of deye7oping springs
 and building small reservoirs are de
 scTibed, and the installation and op
 oratIon Of small pumping plants ara 1 discussed.
 The irrigation investigations car
 ried on by this office for the last ter years have had for their primary oh iect the seeming Of the best use o the available water supply. Tn, measurements made have shown large losses of water by seepage from a
 nals. by evaporation from fields, by percOlatiOn beyond the reach of plan | roots and by wastesdI use. This ar ticle brings together the results O all the measurements Of losses mad, by this office, and describes the meas ures used to prevent them. It Is large ly compilation from previous reports
 and brings all this natter together ir
 a single article.
