From tlie conflicting opinions of scientific men, based on 
chemical analysis, as to both the feeding and manuring value of 
straw, and the almost contradictory statements of other writers 
on this subject, — the large promises of direct profit held out by- 
some from the combination of straw-chafF with richer food in 
cattle feeding, contrasted with the assertions of others that how- 
ever high may be the true theoretic value of straw for feeding, 
still it will not answer to buy rich food for the purpose of mixing 
with straw-chaff, — we turn with satisfaction to the practical good 
sense of the author of the present Essay. 
The highest service which can be at present rendered to agri- 
culture is, perhaps, that of the practical man who, informing his 
mind, and shaping his observations by the light of scientific 
speculation, will address himself methodically to put things to 
the proof under his own eye ; testing, measuring, and weighing, 
not estimating results, yet making due allowance for the influence 
which disturliing causes exercise on the average result as com- 
pared with the maximum effect which can be produced at some 
short and picked moment of time. 
In this sense our author seems to be truly practical, and if he 
leans a little to the old-fashioned side, that is the safe side for 
him who is not unwilling to test and try Avell recommended
