In September of the next year, with the birth of the second, Charles Frewen, there befell Fleeming a terrible alarm and what proved to be a lifelong misfortune. Mrs. Jenkin was taken suddenly and alarmingly ill; Fleeming ran a matter of two miles to fetch the doctor, and, drenched with sweat as he was, returned with him at once in an open gig. On their arrival at the house, Mrs. Jenkin half unconsciously took and kept hold of her husband's hand. By the doctor's orders, windows and doors were set open to create a thorough draught, and the patient was on no account to be disturbed. Thus, then, did Fleeming pass the whole of that night, crouching on the floor in the draught, and not daring to move lest he should wake the sleeper. He had never been strong; energy had stood him instead of vigour; and the result of that night's exposure was flying rheumatism varied by settled sciatica.
Sometimes it quite disabled him, sometimes it was less acute; but he was rarely free from it until his death. I knew him for many years; for more than ten we were closely intimate; I have lived with him for weeks; and during all this time, he only once referred to his infirmity and then perforce as an excuse for some trouble he put me to, and so slightly worded that I paid no heed. This is a good measure of his courage under sufferings of which none but the untried will think lightly. And I think it worth noting how this optimist was acquainted with pain. It will seem strange only to the superficial. The disease of pessimism springs never from real troubles, which it braces men to bear, which it delights men to bear well. Nor does it readily spring at all, in minds that have conceived of life as a field of ordered duties, not as a chase in which to hunt for gratifications. 'We are not here to be happy, but to be good'; I wish he had mended the phrase: 'We are not here to be happy, but to try to be good,' comes nearer the modesty of truth. With such old-fashioned morality, it is possible to get through life, and see the worst of it, and feel some of the worst of it, and still acquiesce piously and even gladly in man's fate.
Feel some of the worst of it, I say; for some of the rest of the worst is, by this ****** faith, excluded.
It was in the year 1868, that the clouds finally rose. The business in partnership with Mr. Forde began suddenly to pay well; about the same time the patents showed themselves a valuable property; and but a little after, Fleeming was appointed to the new chair of engineering in the University of Edinburgh. Thus, almost at once, pecuniary embarrassments passed for ever out of his life.
Here is his own epilogue to the time at Claygate, and his anticipations of the future in Edinburgh.
' . . . . The dear old house at Claygate is not let and the pretty garden a mass of weeds. I feel rather as if we had behaved unkindly to them. We were very happy there, but now that it is over I am conscious of the weight of anxiety as to money which I bore all the time. With you in the garden, with Austin in the coach-house, with pretty songs in the little, low white room, with the moonlight in the dear room up-stairs, ah, it was perfect; but the long walk, wondering, pondering, fearing, scheming, and the dusty jolting railway, and the horrid fusty office with its endless disappointments, they are well gone. It is well enough to fight and scheme and bustle about in the eager crowd here [in London] for a while now and then, but not for a lifetime. What I have now is just perfect. Study for winter, action for summer, lovely country for recreation, a pleasant town for talk . . .'
