"The dredges on this pattern, used in Britain for ten years after their first introduction, about the year 1838, were usually small and rather heavy, not more than 12 to 15 inches in length, by 4 or 4.5 inches in width at the mouth.

Each sieve has a pair of iron handles through which the hand can pass easily, and the handles of the largest sieve are made long, so that the whole nest can be lifted without stooping or putting the arms into the water." — Encyclopedia Britannica, 1893
