This came as a surprise to Daniel, but he did in fact find something to say. "During the Plague Year I tutored this man’s father, the young Charles Comstock, in Natural Philosophy, and we spent many hours studying the compression and rarefaction of gases in the engines conceived by Mr. Boyle, and perfected by Mr. Hooke; the lesson was not lost on young Charles; two score years later he passed it on to young Will at their farm in Connecticut, and it was my very great pleasure to visit them there, from time to time, and to witness those lessons being taught so perfectly that no Fellow of the Royal Society could have added what was wanting, nor subtracted what was false. Will took up those lessons well. Fate returned him to England. Providence supplied him with a lovely Devonshire wife. The Queen gave him an Earldom. But it was Fortune, I believe, that brought him together with the Engineer, Mr. Newcomen. For in the Engine that Newcomen has fabricated at Lostwithiel, the seed that was planted at Epsom during the Plague, England’s darkest hour, has flourished into a tree, whose branches are now bending ’neath the burgeoning weight of green Fruit; and if you would care to eat of it, why, all you need do is water that Tree a little, and presently the apples shall fall into your hands."
