These were his moments of occupation, but he contrived to find moments of amusement besides, which were devoted to the breeding of pigeons, and collecting of insects, which latter amusement he pursued with such success, as to form a cabinet containing no fewer than 4000 specimens of flies, "collected," he says, "at the expense of a great deal of time, a great deal of money, and a great deal of vast and actual labour,"--for all of which, no doubt, the entomologist will deem him sufficiently rewarded. He appears in old age to have entertained a peculiar relish for the recollection of these pursuits, and calls to mind a part of Surrey where there was a very famous fly, and a part of Kent where there was another famous fly; one of these was called the Camberwell Beauty (which he adds was very ugly), and another, the Dartford Blue, by which Dartford Blue he seems to have set great store; and which were pursued and caught in the manner following, in June, 1794, when they regularly make their first appearance for the season. Being engaged nightly at Sadler's Wells, he was obliged to wait till he had finished his business upon the stage: then he returned home, had supper, and shortly after midnight started off to walk to Dartford, fifteen miles from town. Here he arrived about five o'clock in the morning, and calling upon a friend of the name of Brooks, who lived in the neighbourhood, and who was already stirring, he rested, breakfasted, and sallied forth into the fields. His search was not very profitable, however, for after some hours he only succeeded in bagging, or bottling, one "Dartford Blue," with which he returned to his friend perfectly satisfied. At one o'clock he bade his friend good by, walked back to town, reached London by five, washed, took tea, and hurried to Sadler's Wells. No time was to be lost--the fact of the appearance of the "Dartford Blues" having been thoroughly established--in securing more specimens; so on the same night, directly the pantomime was over, and supper over, too, off he walked down to Dartford again, found the friend up again, took a hasty breakfast again, and resumed his search again. Meeting with better sport, and capturing no fewer than four dozen Dartford Blues, he hurried back to the friend's; set them--an important process, which consists in placing the insects in the position in which their natural beauty can be best displayed--started off with the Dartford Blues in his pocket for London once more, reached home by four o'clock in the afternoon, washed, and took a hasty meal, and then went to the theatre for the evening's performance.
