Woods of _Mulberry-Trees_, so many Silk-Worms, and such immense Quantities of Silk, that a Person may there purchase ten silken Suits of Cloaths at an easier Rate, than he can have one of Cloth in any Part of _Europe_. The _Chinese_ prune their _Mulberry-Trees_ every Year, as the _Europeans_ do their Vines; nor do they suffer them to grow up into tall Trees, because they have found from long Experience, that the Leaves of the smallest Trees produce the finest Substance for Silk, and the best Thread: For which Reason, they justly distinguish between the first and second Weaving of the Thread: The former is produced when the Worms are nourished by the Leaves which appear in the _Spring_, and are soft and delicate: The latter is, when they are fed upon the _Summer_ Leaves, which are coarse and hard; so great is the Difference of Work produced by these Animals only by a Change of Food." If this Account of the Nourishment of Silk-Worms is true, as we _Europeans_ find it by Experience, so it is equally certain, that there is as great a Difference between those Leaves of the _Chinese Tea_, or _European Chamelæagnus_, which appear in the _Spring_, and those which are produced in the _Summer_, as I have all along insinuated in this Work. By this remarkable Passage of the anonymous Author, I am more and more convinced, that the vernal Leaves of the _Chamelæagnus_, or _European Tea_, are possessed of different Virtues from those which appear in the _Summer_, when the Sun has entered _Leo_: And those who will not grant this Truth, are confuted by the palpable Instance drawn from the Nourishment of the Silk-Worms. By way of Digression, I shall intreat every Lover of Truth, to throw the Leaves, (not the Shrub, Flowers, or Seeds) of the _European Chamelæagnus_, which, when dry, have no Scent upon live Coals, and do the same with an equal Quantity of _Chinese Tea_, tho' in different Rooms, and by the exact Resemblance of the Smell diffused by each, he will be convinced that the _Chamelæagnus_ is a Plant of the same Species with _Tea_.
