862 EXPEKIMENT STATION RECORD. 



The wood pulp industry of Canada {Bnl. Sac. Cent. Ford. Bdg., S [1901), No. 5, 

 pp. 2D'^-305). — A description is given of the wood pulp industry of Canada, and 

 the forest resources of that country are compared with other regions. Each province 

 of Canada, with the exception of Manitoba and the Northwest Territories, produces 

 great quantities of spruce timber which is particularly adapted to the production of 

 wood pulp. The increase in the use and production of wood pulp for the last 10 

 years is shown, and the possibilities of Canada for supplying this material are 

 pointed out. 



SEEDS—WEEDS. 



A report on cooperative seed testing, F. Nobbe {Landw. Vers. StaL, 56 {1901), 

 No. 2-3, pp. 177-185). — A report is given on the fifth cooperative experiment in test- 

 ing red clover, sainfoin, perennial rye grass, meadow fescue, and beet seed. The 

 seeds used in this experiment were from single lots which were thoroughly mixed 

 and then distriVjuted to the 30 stations in the seed control union of German)^ The 

 different kinds of seeds were to l)e tested at the different stations under identical 

 conditions as to temperature, moisture, light, etc. Rejiorts were received from about 

 half of the stations, which show wide variation Ijetween the maximum and minimum 

 percentages obtained by the several observers. In the case of the clover seed there 

 was a variation of 2.27 per cent in purity and 7.61 per cent intrinsic value. The 

 variation of sainfoin seed reported was 1.62 per cent in purity and 21.15 per cent in 

 intrinsic value. The perennial rye grass gave a maximum and minimum range of 

 3.63 per cent jiurity and 14.40 per cent intrinsic wortli. Meadow foxtail gave 19.99 

 per cent as a range of purity determination and 12.38 per cent intrinsic value. The 

 beet seed samples showed a variation of 3.43 per cent purity and 11.5 per cent in 

 actual value. While there appears to be a wide range in these figures, except in the 

 purity of the meadow foxtail and the intrinsic value of the sainfoin, the figures fall 

 within the limits allowed by the regulations of the seed control union. In the 

 results of tests of soft grass and blue grass seed departures from the normal, while 

 large, fall within the limit of 8 per cent, which is allowed by the seed control 

 regulations. 



Report of the Goteborg and Bohus Seed Control Station for the year ended 

 June 30, 1901, J. E. Alex {Red. GiJIeborgs och Bohua lans frohmtrollanst., 1900- 

 1901. Goieborg, 1902, pp. 12). — A report is given on the seed investigations con- 

 ducted at the station during the year 1900-1001. In all, 356 lots of seed were 

 inspected and the analytical data are given in detail. A schedule of charges for seed 

 investigation is appended to the report. 



Studies in weeds, W. Carruthers {Jour. Roy. Agr. Soc. England, 62 {1901), pp. 

 249-256, figs. 8). — Brief notes are given on a number of more or less troublesome 

 weeds, among them Ononis arven.m, .Egopodhun podagraria, Carduus acaulis, dog 

 camomile, ragwort, etc. Notes are also given on the relative value of different brome 

 grasses and bent grasses for forage and pasture. 



The horse nettle and buffalo bur, J. C. Arthur {Indiana Sta. Rpi. 1901, pp. 

 9-19, ph. 3, fig. 1, map 1). — A description is given of the horse nettle {Solanuin caro- 

 linense) and the l)uffalo bur {S. rostratum). The relationship of these weeds is pointed 

 out and the distribution throughout the State is indicated. One or both species have 

 been reported from about one-third the counties of the State. Suggestions are given 

 for their eradication, and attention is called to the fact that the horse nettle being 

 perennial, particular care will have to be given to prevent the multiplication of the 

 individual plants. This weed may be eradicated by continued growing of hoed crops 

 or by some thickly growing crop which will smother it out. The Jniffalo bur is an 

 annual plant and for its extermination only requires that it be kept from seeding, 

 which can be done by cutting or pulling plants during the early part of the season.
