On the Absence of Earthworms from the Prairies of the Canadian North-West

Abstract

NOT by any means the least remarkable of the very notable series of works which Mr. Darwin has given to the world is that which came last from his pen but a short time previous to his lamented death. Dealing, as it does, with effects which, when looked at in the detail, are exceedingly small and insignificant, but, when viewed in the aggregate, are shown to be of surprising importance, the “Vegetable Mould and Earthworms” must certainly rank as a most strilingly interesting work.
