the best authorities on agriculture, and set apart five or even one or 

 two acres upon which to experiment vnth. all varieties of crop and 

 manure that would hold out prospects of success. Thus there 

 would be no fear of incurring any serious loss or disappointment. 

 It takes energy and patience with study both of chemistry and 

 agriculture to make a good experimenter on a plot of one acre, and 

 this method alone when thoroughly and repeatedly worked out can 

 give success on the more extended area of the farm. 



Young men designing to enter on an agricultural career w^ould 

 need to devote as much time to education if success is to be assured, 

 as would be needed if they intended adopting the professions so 

 called. For it is an extensive and complicated subject, and can give 

 scope to the most accomplished intellect in studying its mysteries. 



Chemistry does and will do much for agriculture ; it explains 

 the changes taking place in and products resulting from vegetation ; 

 it gives, in competent hands, the composition of the active consti- 

 tuents of the soil and suggests the most appropriate additions 

 thereto, or in other words directs experiment, the crucial and 



TRUSTWORTHY TEST. 



When the demand becomes sufficiently extensive for commercial 

 success, it will produce the necessary plant food in soluble form 

 from apatite rock, phosphates from the so called marie deposits 

 existing in the province, from the bones and animal substances that 

 now go to waste, from ammoniacal gas liquor, sewage, sea weed, 

 and such like, that are mines of wealth to the farmer as well as 

 manufacturer, when the occasion calls forth some of the resources 

 of Chemistry.

Each animal* begins life at the same point of departure — the 

 egg — with every other, and certainly all the Vei-tehrata, in the early 

 stages of their development, pass through apparently precisely the 

 same transformations, but all except man at some stage become 

 specialized ; he alone continuing a course of harmonious develop- 



* Except certain of the lower Grades in which a whole community is developed 

 from the product of a single egg, by budding, subdivision, &c.
