"Is the leech used to bleed people when they are ill ever found in the ponds of this country?" asked Willy. I believe it is rarely met with now-a-days; most of the leeches used in medicine are imported from Spain, Hungary, the south of France, and Algeria; many millions are brought every year to this country. The medicinal leech, was, however, once pretty common in the lakes and pools of the north of England. The poet Wordsworth introduces us to an old leech-gatherer lamenting the scarcity of the animals in the following lines: "He with a smile did then his words repeat And said that gathering leeches far and wide He travelled; stirring thus about his feet The waters of the pool where they abide. Once I could meet with them on every side; But they have dwindled long by slow decay; Yet still I persevere and find them where I may." This sonnet was written in 1807, and when we consider the immense numbers used in medicine, and the utter neglect of leech culture in this country, we shall cease to wonder that native leeches are very scarce. It is said that four only of the principal dealers in London import every year more than seven million leeches. The annual demand in France was estimated in 1846 to be from twenty to thirty millions; Paris requiring three millions a year. "I should be very sorry, papa," said Jack, "to walk about like the old man in the lines you quoted just now, with bare legs in the water, making them a bait for leeches. Ugh! it is horrible to think of; they must suck a good deal of blood from the man's legs." There is nothing like being used to a thing, and when you remember that many people derive their whole support from the leeches they gather, you will not wonder that they do not fear a few leech bites. I do not suppose they lose much blood; no doubt the gatherers pick them up pretty quickly and put them into their collecting cases; besides the chief flow of blood from a leech-bite occurs after the leech has been removed; the flow is encouraged by the application of warm fomentations, but the cold water of a pool would stop the flow of blood in the case of the man's legs. We ought to be thankful for the existence of an animal which is of such immense service to mankind. I suppose it was the appreciation of their value in medicine that induced French ladies, about forty-five years ago, to regard leeches with especial favour. Many people remember the Cochin-China _mania_ and the sea-anemone _mania_, but, May, what will young ladies say to the fact that in 1824 there existed in France a _mania_ for leeches? The most enthusiastic admirer of Cochin fowls or sea-anemones would never have thought of carrying her admiration of her pets so high as to wear on her dress figures of these animals; but we learn from a French writer that there might have been seen at that period elegant ladies wearing dresses _a la Broussais_ on the trimming
