It was not very long after the above adventure, that Lambert experienced an escape from a danger much more alarming, and from the consequence of which no human exertions could possibly have preserved him. He was one of the numerous inhabitants of Leicester, whom the memorable conflagration at the house of a well known bookseller, now resident in the metropolis, attracted to the spot. It was dark, the fire was then raging with the utmost fury, and Lambert passed along under a wall, which, from the falling of the others to which it had once been joined, now stood completely detached. When he had reached the extremity, an acquaintance whom he accidentally found there, congratulated him on his narrow escape, at the same time pointing to the wall. Lambert, totally unconscious of the risk to which he had been exposed, and now standing in a line with the wall, observed with horror that it rocked to and fro like corn in the breeze, and not many moments elapsed ere it fell with a tremendous crash. His father having resigned the office of keeper of the prison, Daniel succeeded to the situation. It was within a year after this appointment that his bulk received the greatest and most rapid increase. This he attributed to the confinement and sedentary life to which he was now obliged to submit, which produced an effect so much the more striking, as, from his attachment to sporting, he had previously been in the habit of taking a great deal of exercise. Though he never possessed any extraordinary agility he was still able to kick to the height of seven feet, standing on one leg. About the year 1793, when Lambert weighed 448lbs, he had occasion to visit Woolwich, in company with the keeper of the county jaol of Leicester. As the tide did not serve to bring them up again to London, he walked from Woolwich to the metropolis, with much less apparent fatigue than several middle sized men who were of the party. The inhabitants of Leicester are remarkable for their expertness in swimming, an art which they are encouraged to practise by their vicinity to the river Soar. From the age of eight years Lambert was an excellent swimmer, and such was his celebrity, that about ten years ago, all the young people in his native town, who were learning to swim, resorted to him for instruction. His power of floating, owing to his uncommon bulk, was so great that he could swim with two men of ordinary size upon his back. He has been heard to relate that, on these occasions, when any of his young pupils manifested any timidity, he would convey them to the opposite bank of the river from that on which they layed their clothes, and there leave them to find their way back as well as they could. By this means, they soon acquired that courage which is so indispensably necessary to the attainment of excellence in the art of swimming.
