Notes and tabulated data are also given for 14 varieties of winter 

 wheat. De Kieti (red) and Richelle de Naples (white), from see<l 

 imported from France by this Department, gave promising results.

Experiments with corn, W. H. Newman, M. S. — These were ^>ith 

 fertilizers on drained and undrained land, and with i)eas and melilotus 

 as soil renovators, in continuation of the experiments reported in Bul- 

 letin No. 10 of the station (see Experiment Station Record, vol. ii, p. 

 473). The results for 1891, as described in notes and tables, confirm 

 those of the previous year in indicating that drainage is more profitable 

 than tlie ajjplication of fertilizers on "black slough" bottom land, and 

 that peas and melilotus furnish the cheapest and bevSt means for improv 

 ing the canebrake lands.

Analyses of soils (pp -3-o0). — Analyses of 49 samples of soil 

 from the Sierra foothills. Great Valley, Coast Range, and southern 

 California. 



Analyses ok waters (pp. 61-82). — Analyses of «54 sami)les of water 

 from streams, lakes, springs, common wells, and artesian wells. 



Analyses of rock, clay, makl, peat, and gvi'sum (pp. 83-8r)). — 

 Analyses of i)hosphate rock, soft limestone, clay, cement rock, clay and 

 limestone, marl, peat, and gypsum. 



Alkali (j)]). ST-lOo). — Tiiis includes tlie synoitsis ot a lecture deliv- 

 ered at a farmers' institute by K. W. Hilgard, Ph.D., on alkali, its nature, 

 causes, and repression; analyses of 11 samples of alkali; and a report 

 by M. E.Jaffa, Pii. B.,ou further experiments on the reactions between 

 alkali sulphates, calcic carbonate, and free carboni<' a<id. 



[A sample of alkali from I'lcasaiit Valley], a whitish powder accniiiiilating by the 

 •vaporation of the waters of tJie valley, eonsists chiefly of Hul])hatu of soda 

 (Glauber's salt) with small amounts of carbonate of soda (s.-il soda) and common 

 salt. Tli« waters of the streams contain 119 f^'iiins per gallon of this [former] salt 

 and are thus renilered unlit for domestic use. • • • [The following is the com- 

 position given of a sample from Kern Island. Kern County], a surface crust heavily 

 clmrged witli soluble salts, from tlir etfects of surface evaporation.
