3. do. Guano, 1 cwt. ; mixed with earth, and do. do. 
Observations. — The whole came up well, no difference being 
visible in any of the three for some lime, when No. 3 took the 
lead. All the plots throve well, and, though sown late, at harvest 
promised a very fair crop. The clover seeds came equally well 
in all the patches. On reaping, September 7, No. 3 still had 
the advantage in weight of straw ; No. I being also a shade better 
than No. 2 in quantity of straw. No. 2, however, showed some- 
what similar effects from the application of salt that we observed 
in the other experiments on barley ; — the straw was whitened, 
sooner ripe, and promised a better yield. The seeds were 
equally good throughout. The following were the results from 
each portion : — 
1. 370 sheaves, yield. 114'21bs. of straw, and OOSlbs. of grain, weigh. 561bs. per bush.

Conclusions. — In this experiment we note — 
1. That guano and rape-dust, in comparative effect, are nearly 
equal ; from want, however, of a j)atch loitliout manure, we are 
unable to see what was tlie positive effect of each ; hence we 
cannot say whether the equal yield from each plot arises from
