"That they do wander6 from one place to another is evident, as I am assured that they have been found in ponds in Richmond Park, which had been previously cleaned out and mudded, and into which no water could run except from the springs which supplied it.7 An annual migration of young eels takes place in the River Thames in the month of May, and they have generally made their appearance at Kingston, in their way upwards, about the second week in that month, and accident has so determined it, that, for several years together it was remarked that the 10th of May was the day of what the fishermen call eel-fair; but they have been more irregular in their proceedings since the interruption of the lock at Teddington. These young eels are about two inches in length, and they make their approach in one regular and undeviating column of about five inches in breadth, and as thick together as it is possible for them to be. As the procession generally lasts two or three days, and as they appear to move at the rate of nearly two miles and a half an hour, some idea may be formed of their enormous number.
