228 EXPEEIMENT STATION EECORD, 



botanical composition of tlie herbage of the plats (before the manures are 

 added) in relation to the type of grass land to which they belong, and the 

 prevailing meteorological conditions. Factors which are indirectly dependent 

 on the nature of the manures added are the role the manure exercises in merely 

 disturbing the prevailing equilibrium, and the effect the treatment may have 

 on the physical, chemical, and biological properties of the soil. Factors which 

 are dependent on the chemical composition of the manures added are the in- 

 dividual appetites of the several species for the particular plant foods in the 

 form they are added, and the physiologically depressing effect particular 

 manures may produce on individual species. 



A bibliography of 11 titles is included. 



Experiment tanks for the determination of the water requirements of the 

 principal meadow and pasture grasses, C. von Seelhorst {Jour. Landiv., 62 

 (1914), No. 4, pp. 337-34 'f, fiO- !)■ — I'liis article describes concrete sunken tanks 

 and methods employed for the determination of water requirements of grasses. 



Grasses and clovers on the Murrumbidgee irrigation area. — A spring trial, 

 R. W. McDiAUMiD (Agr. Gaz. N. S. Wales, 26 (lUlo), No. 2, pp. 127-129).— This 

 article gives results of the first season's growth of sin-ing sowings of the fol- 

 lowing grasses and clovers: Strawberry clover {Trlfolium fragijerum), Chilian 

 clover (T. pratcnse perenne), Egyptian clover (T. alexandrinum), white Dutch 

 clover {T. rcpens), Rhodes grass {Chloris gayana), Phalaris huJbosa, Texas 

 blue grass (Poa arachnifcra) , prairie grass {Bromus unioloides) , perennial rye 

 (Lolium percnnc), tall fescue (Festuca arundinacea) , Hungarian brome grass 

 (B. inermis), cocksfoot {Dactylis glomcrata), Sudan grass {Andropogon sor- 

 ghum), and panic grasses (Panicum flavidum and P. hulhosuni) . Among these 

 it is noted that Rhodes grass, Sudan grass, panic grass, Hungarian brome 

 grass, and tall fescue were most successful. The clovers were unsuccessful. 



Results of experiments on the manuring of grass carried out at Moorlands 

 Pami, Kineton, Warwickshire, E. Parke (London, 1013, pp. 3). — This article 

 gives results of the twelfth season of experiments on the manuring of grass, 

 carried out at Moorlands Farm, Kineton, with the cooperation of Dr. Bernard 

 Dyer. 



It is stated that in general " the unmanured land is still conspicuous for the 

 poor, wiry nature of the grass and the abundance of plants which, in a pasture, 

 may be regarded as weeds. On all the manured plats, on the other hand, there 

 is an abundant growth of rich grass. Where phosphates, or phosphates and 

 potash salts, have been continuously applied without nitrogen, the growth of 

 plants of the clover kind is most conspicuous; while on the plats on which 

 nitrate of soda has been continuously used without phosiihates or potiish (a 

 mode of manuring which on general principles is not to be recommended), the 

 grasses, as distinguished from clovers, are most prominent. The best herbage, 

 however, in which clovers and grasses appear to flourish with equal vigor 

 and luxuriance, is still found on the plats on which both phosi^hates and 

 nittate are used every year." 



Universal hay tonnage table, Mollie D. Chesnut (Torringion, Wyo.: 

 Author, 1915, pp. 32). — Tables are given showing the number of tons of hay in 

 a stack, according to the required measurement of round stacks, and based 

 upon United States Government rules. 



Western hay tonnage table, Mollie D. Chesnut (Author: 1914, pp. 12). — A 

 table showing the tonnage when width, overthrow, and length of stack are 

 given for alfalfa and wild hay, with rules for computation. 



Grain inspection in Canada, R. Magill (Ottawa: Govt., 1914, PP- 64, flffS- 

 34). — ^This describes and illustrates the methods of sampling, weighing, and 

 testing grain in western Canada.
