Connecticut State Station, Bulletin No. 108, May, 1891 (pp. 11). 



Examination of the seed oe orchard grass (pp. 2-4). — The 

 tabulated results are given of botanical analyses and germination tests 

 iiiitde at the station of 17 sam])les of orchard-grass seed, of Avhich -were 

 bought of seedsmen in the ytatc, from Boston, and 5 from New York. 

 The results of these examinations are summarized as follows: 



Of the 17 samples 1 sample contained as mncli as 98.8 per cent of pnre seed, the 

 remainder being chaff. Anotlier contained no orcliard-grass seed whatever, and 

 consisted mainly of LoUiim perenne, or perennial rye grass. Excluding this sample, 

 the other 16 samples contained on the average 77.4 per cent of pure seed. 



Seven out of 16 samples contained notable quantities (from 8.3 to 35.5 per cent) 

 of seed of perennial rye grass, which is less valuable and sells at a lower price. 

 "Tested" orchard-grass seed is quoted at 11 cents per pound and tested perennial 

 rye grass at 4^ cents. A single sample contained 14.1 per cent of a species of Bromus, 

 probably scealinus, or chess. 



In 1 sample as high as 88 per cent of the orchard-grass seed sprouted, in anotlier 

 as low as 4.5 per cent, and on the average of 16 samples .50 per cent. 



Taking tne 16 samples together, the average quantity of pure orchard-grass seed 

 which was capable of sprouting was 40 per cent; i. e. out of every 100 pounds 

 liouglit 40 ])Ounds was jjure, live seed. Probably the quantity that would produce 

 healthy plants was less than this. 



Asii ANALYSIS OF Whtte Globe ONIONS (pp. 4, 5). — Twenty-tvTo 

 fair-sized White (Jlobe onions were selected from several barrels for 

 analysis. The fresli onions contained 0.27 per cent of nitrogen and 0.48 

 per cent of ash. The composition of the pure ash and the calculated 

 amount of ash ingredients in 1 ton of onions are given as follows:
