England employed to ascertain the amount of the rainfall, and 

 we can boast that in British North America the science of 

 Meteorology is taught in our Colleges and Grammar Schools. 

 Observatories have been established through the generosity of our 

 Government at those points of great importance, Halifax and St. 

 Johns, N. B. All that we now require is unity of purpose so as 

 to bring our united efforts to a useful end. We propose to offer 

 suggestions in reference to the organization of some plan of action 

 in a future number. C. S.
