MANURING EXPERIMENTS WITH PADDY RICE (SECOND YEAR). 
vigor and height were those without nitrogen, which turned, 
however, pale an at early period of growth and ripened about io 
days before all the other plots ; the plants without phosphoric 
acid and those without any manure represented essentially the 
same appearance, remaining very small, with a dark green 
colour, and exhibiting less inclination to ripen. 
The yield of grain and straw of the single plots will be found 
in the appendix. In the average of three equally manured 
plots we obtained the following produce :
