EXPERIMENT STATION RECORD. 



and the main crop 5 to G days earlier. The results are given in the 

 following 1 table: 



Average growth of peas from 4 heavy and 4 light needs. 



The results with beans were very similar to those with peas, both as 

 regards growth and earliness. The average weight of fresh roots of 2 

 bean plants from large seed was 13.35 gm. and from small seed 4.3 gm. 



An experiment was made with a number of plants to compare the 

 germination of heavy and light seed. From 50 to 100 heavy and light 

 seeds of each variety were planted. The results are given in tabular 

 form. The authors consider the experiment too limited to warrant 

 conclusions being drawn with reference to germinative power, but with 

 reference to growth of seedlings the results were quite marked, as is 

 shown in the following table: 



Weight of heavy and light seed and of seedlings from the same. 



Seed production and saving, A. J. Pieters ( U. S. Uepi. Ayr. Yearbook 1896, pp. 

 207-216, figs. 8). — Seed production is popularly discussed from both botanical aud 

 practical points of view. The effects of cross aud self fecundation are considered, 

 and some of the agencies effecting cross pollination are noted. Home growing, har- 

 vesting, aud storing seed are briefly considered. 



The preparation of seed to prevent its being eaten by birds, M. Hoi i maxn 

 (Dent. Landw. Presse, 24 (1897), No. 82, p. 750). — Directions are given for the treat- 

 ment of different kinds of seed and the results of experiments to determine the effect 

 of the treatment on the power of germination are reported. 



Migration of weeds, L. H. Dewey ( U. S. Dept. Agr. Yearbook 1896, pp. 263-286, 

 figs. 15). — The various agencies, both natural and artificial, which aid the migration 

 of weeds, the geographical distribution of several prornineut weeds, the direction 

 of weed migration, the development of migratory habits by cultivation, etc., are 

 considered.
