REPORT ON VARIOUS MANURES AT CHISWICK. 41 
Box 3 (Ammonia-salts). Healtliy well-developed plants of a 
bluish-green colour, 11 inches in height, with little tendency to 
flower. The best plants of any. 
Box 4 (Nitrate of soda). Plants healthy, slightly injured by 
frost, of a bluish-green colour, 10 inches high, with a slight ten- 
dency to flower. 
Box 5 (Mineral and ammonia). Plants well developed, but 
sickly and injured by frost, of a yellowish-green colour, 10| 
inches high, with little or no tendency to flower. 
Box G (Mineral and nitrate). Plants fairly healthy and well 
developed, injured by frost, bluish green, 81 inches high. 
On comparing the state of the plants in the six boxes of Bac* 
tylis in October with their condition in July, relatively little dif- 
ferences were observable. 
ii. Antnoxanthum. 
Box 1. Plants healthy ; leaves broad, pale green, slightly injured 
by frost. Average height 6 inches. No tendency to flower. 
Box 2. Plants healthy j leaves broad, darker than in No. 1, 
slightly injured by frost ; average height 7 inches. 
Box 3. Plants healthy, dark green, in better condition than in 
the preceding ; height 7 inches. 
Box 4. Plants healthy, vigorous \ leaves broad, yellowish, much 
injured by frost ; height 9 inches. A slight tendency to flower. 
Box 5. Plants healthy, strong, frost-bitten ; height 9 inches. 
No tendency to flower. 
Box 6. Plants healthy ; but leaves not so broad as in the three 
preceding ; height 8^ inches. No flowers. 
The most noteworthy circumstances in comparing the state of 
the plants in October and in July were the opposite conditions 
shown in boxes 3 and 4 and in 5 and 6 respectively : thus in 3 
(ammonia salts) the plant had relatively declined after July, while 
in 4 (nitrate of soda) an equally great rise in October was noted as 
compared with the state in J uly. In 5 (ammonia and mineral) 
there was a slight rise in October, as there was also in 2 (mineral) ; 
and in 6 (ammonia and nitrate) there was a fall corresponding to 
that of the plants in 3 (ammonia) . 
iii. Lolium, 
Box 1. Healthy, slightly touched by frost, 8 J inches high. No 
tendency to flower.
