BEPOET ON VARIOUS MANURES AT CHISWICK.

corresponding to the increased rainfall. In boxes 2, 3, 4, 5 no 
perceptible relation was observable. In box 6 a slight check, cor- 
responding to deficient rain, towards the end of May was noticed. 
xii. Garum Carid. 
Box 1. Uniform minimum, ^ot fully developed on July 1. 
Average height 6 inches. Bright green. 
Box 2. Uniformly low degree of vigour. Average height in 
July 7 inches. 
Box 3. Medium degree of vigour. Slight rise in June ; fall 
towards the end of the month. Average height 7 J inches. 
Box 4. Medium. Slight fall in June ; rise at the end of 
the month. Average height, July 1, 6| inches. 
Box 5, Uniformly high, leaves longer than in the others. 
Average height 9 inches. 
Box 6. Uniform maximum. Average height 9 inches. Eather 
better crop than 5. 
All the plants were healthy, but little developed, and with no 
trace of flower. 
In the plants in 1 and 2 no relation to temperature and rainfall 
was noticed. In 3 a slight increase in vigour in the middle of 
June, in proportion to the increased rain and heat, was observ- 
able, in 4j a slight increase, in proportion to the increased rain 
and heat, in the middle of June. In boxes 5 and G no relation 
could be traced. 
Notes on the Coraparative Effects of tlie Several Manures on the 
Various Species of Plants. 
In the preceding notes the relative condition of the plants of 
the same species in the six boxes, one unmanured, five manured, 
has been briefly recorded. It is quite as instructive to compare 
the efl*ects of each kind of manure on the twelve plants of dif- 
ferent species. 
JBox 1. Vnmanured. 
In almost all cases the unmanured plants in box 1 presented, 
with little or no fluctuation,the minimum de ree of vigour through- 
out the experiment. Of ii. {Anthoxanthum) , however, the general 
condition of the plants in the unmanured box was better than in box 
2 (min. manures). The most remarkable exception occurred in the
