Many able Gardeners and Husbandmen are yet Ignorant of the Reason of their Calling; as most Artificers are of the Reason of their own Rules that govern their excellent Workmanship. But a Naturalist and Mechanick of this sort is Master of the Reason of both, and might be of the Practice too, if his Industry kept pace with his Speculation; which were every commendable; and without which he cannot be said to be a complete Naturalist or Mechanick.
