Dried bean production in Illinois, C. E. Dxjbst {Illinois Sta. Circ. 201 

 {1911), pp. 8). — A general discussion of the production and harvesting of heans 

 for drying as human food, together with a brief note on insects and diseases. 



Field bean production, R. W. De Baun (xVeic Jersey Stas. Circ. 10 {1917), 

 pp. 4)- — The methods for production of field beans in New Jersey are briefly 

 discussed. 



Studies of variation and correlation of weight and sugar content of beets, 

 especially sugar beets, W. Oetken {Landw. Jahrb., 49 {1916), A'o. 1, pp. 1-lOS. 

 fif/s. 4)- — The author outlines the object of his investigations and describes the 

 material used and the methods employed in connection with a series of experi- 

 ments previously noted (E. S. R.. 35, p. 640). A number of formulas are pre- 

 sented and explained for determining the mean, the standard of deviation, the 

 coefficient of variation, regression, the correlation coefficient, the excess, etc. 



The variability in weight and sugar content was studied in respect to the 

 Individual and to a series of individual.s. Considerable data are presented in 

 tabular form and discussed in detail. 



A list of 75 articles comprising the literature cited is appended. 



Corn, F. App {Neio Jersey Stas. Circ. 69 {1917), pp. 7). — The advantages of 

 an increased corn acreage under present food conditions are briefly discussed 

 and the field practices employed in corn production in New Jersey outlined. 



Varieties of cotton, 1916, W. E. Ayres {Arkansas >^ta. Bui. 129 {1917), 

 pp. 5-.?2, fig. 1). — Extensive variety tests with cotton at Scotts. Mena, and 

 Fayetteville and cooperative tests throughout the State are reported, with con- 

 siderable tabulated data. 



The highest-yielding varieties at Scotts were Cleveland, with 946.2 lbs. of 

 lint per acre, and Cook No. 920, with 813.8 lbs. per acre. At Mena Ilalf and 

 Half was first, with 265.4 lb.s. of lint, and Arkansas Trice second, with 225.4 

 lbs. per acre. Brief descriptive data are submitted for the varieties tested at 

 Fayetteville. 



The recurving of milo and some factors influencing it, A. B. Co.xner and 

 R. E. Kari'KK {Texas Sta. Piil. 20J, {1017), pp. ?,-^n. fifjs. i.?).— Experiments 

 were conducted by the authors during lOlfi at Lubbock, Tex., pertaining to the 

 recurving, or " goosenecking," of milo maize, which is deenie<l undesirable on 

 account of the difficulty of harvesting the crop with machinery and the reduc- 

 tion in yield through loss of heads during the early stages of growth. Some 

 conclusive data are presented on the anatomy of the milo maize plant and 

 variation in anatomy of both milo maize and Kafir corn plants under different 

 environmental conditions. No definite CMnclusions are dra^xm as to the funda- 

 mental causes of recurving, although a number of the factors which heretofore 

 were considered responsible for the iihcnomenon have been eliminated and 

 evidence advanced to indicate that recurving is due to the structure and de- 

 velopment of the upper leaf sheath. 



Considerable tabulated data are presented and discussed in detail. The 

 studies are to be continued in the hope of obtaining a proper basis for the selec- 

 tion of strains having erect heads. The observations for the season of 1916 

 may be summarized as follows : 



Tallne.ss or dwarfness In the same strain was a result of the lengthening or 

 shortening of the internode. No apparent difference was observed in the tender- 

 ness of the petluncle of different grain sorghums at similar stages of growth. 

 Dwarfness wds associated with a high percentage of erect heads, while tallness 

 was attended by a high percentage of pendant heads. Rapid growth was con- 

 ducive to tallness and slow growth to dwarfness. 



The removal of a vertical section of the back of the upper leaf sheath always 

 resulted in a complete recurving of the peduncle in the direction of the open-
