 Soc, 10 {1903), No. 4, Pl>- 4S-G1). — This paper is a defense of the author's theory 

 regarding the ascent of sap and a criticism of the conclusions of others relating to 

 tliat theory. 



Formation of the spores in the sporangia of Rhizopus nigricans and of 

 Phycomyces nitens, D. B. S\vin(;le [V. S. Dcpt. Agr., Barexta of I'lant IndiL^try 

 Bui. .37,])p. 40, ph. G). — A technical paper giving the results of studies of the forma- 

 tion of tlu' spores of llhcopui^ n'lgriraiin and of PJnjromyc.es nitens. 



Bacteria in modern economic agriculture, A. Schneider [Pop. Sri. Mo., GS 

 {1903), No. 4', pp- 333-34S). — A popular ac-count is given of nitrogen assimilation by 

 leguminous plants through the bacteria occurring in the tubercles npon their roots. 



Outline of the history of leguminous root nodules and rhizobia, with 

 titles of literature concerning the fixation of free nitrogen by plants, A. 

 Schneider {M'mneaota Bot. Studies, 3. ser., 1903, ]>t. 2, pp. 133-139). — A brief histor- 

 ical resume is given of investigations regarding the assimilation of nitrogen through 

 the root tubercles of leguminous plants, and a list of titles of recent ])nl)lications 

 bearing upon this subject is a[>pended. 



The inoculation of leguminous plants and its practical importance, IIiltner 

 (Clieiii. Zlg.,27 {1903), No. 40, p. Gil). — -A brief general discussion Ijefore the section 

 of agricultural chemistry of the recent lnternatif»nal Congress of Ajiplied Chemistry. 



Alinit, its bacterial composition and physiological role in the soil, Severin 

 ( Vyi'stuik Imp. Buss. Oh.sJi. Akkliiuat. Zliir. I JiH.st. Bukt. Agron. Stantz., No. 9,pp.3G-57; 

 ahs.hi Zhur. Opuitn. Agron. [Jour. PJ.ipf. L(iv(hr.'\, 4 {1903), No. 1, J)p. IIG, 117). — 

 The author investigated a preparation of Alinit o))tained from Bayer's factory and 

 found that it consisted of 2 micro-organisms: (1) Bacillus ellenhachensis, which is 

 described 1)y all investigators, and another — its race variant — differing from the former 

 mainly by its inability to re<lnce nitrates. The author proposes to name it P>. rllen- 

 harliensis (i. When growing in horse manure both races ajjpear to show little activity 

 in destroying organic matter; neither induces ammoniacal fermentation in urine. 

 The author, on the basis of his experiments, concurs with the conclusion of the 

 majority of investigators that Alinit is of no value for agricultural practice. — p.

Michigan mushrooms, E. O. Longyear {Michigan Sta. Bui. 208, pp. 79-100, figs. 

 21). — Descrij)tions are given of a few of the more common edible fungi known to 

 occur within the State. Various species of Morchella and some of the juifflialls are 

 described.

Climatic conditions at California substations, C. H. Shinx ( California Sta. Bui. 

 147, pp. S, 30, 4'"), G3, 90, lOJ). — Observations on temperature, rainfall, frosts, etc., 

 during several years are recorded for the Foothills Substation near Jackson, the 

 Southern Coast Range Substation at Paso Robles, the San Joaquin Valley Substation 

 at Tulare, the Southern California Substation near Pomona, and the Forestry substa- 

 tions near Santa Monica and Chico. 



Meteorological observations, W. T. Ellis, R. Robertson, W. S. Blair, S. A.

 years are recorded.
