It has often been placed on record in American publications during the past thirty years, that in this country the fibrous roots of trees grow during the Winter. By the following from the Gardener's Chronicle, it appears that they also grow in this way in France, though it is not generally believed to be a fact in the experience of planters in England:

" M. Resa, as quoted by M. Micheli, says that the roots of deciduous trees grow in Autumn after the fall of the leaf till the growth is checked, but not altogether stopped by Winter frosts. In the case of Conifers the growth of the roots ceases in Winter, to be resumed in Spring".
