The rule of the service in regard to pensions is very just. A man shall serve till he is sixty before he is entitled to a pension,--unless his health fail him. At that age he is entitled to one-sixtieth of his salary for every year he has served up to forty years. If his health do fail him so that he is unfit for further work before the age named, then he may go with a pension amounting to one-sixtieth for every year he has served. I could not say that my health had failed me, and therefore I went without any pension. I have since felt occasionally that it has been supposed that I left the Post Office under pressure,--because I attended to hunting and to my literary work rather than to postal matters. As it had for many years been my ambition to be a thoroughly good servant to the public, and to give to the public much more than I took in the shape of salary, this feeling has sometimes annoyed me. And as I am still a little sore on the subject, and as I would not have it imagined after my death that I had slighted the public service to which I belonged, I will venture here to give the reply which was sent to the letter containing my resignation. General Post Office, October 9th, 1867. SIR,--I have received your letter of the 3d inst., in which you tender your resignation as Surveyor in the Post Office service, and state as your reason for this step that you have adopted another profession, the exigencies of which are so great as to make you feel you cannot give to the duties of the Post Office that amount of attention which you consider the Postmaster-General has a right to expect. You have for many years ranked among the most conspicuous members of the Post Office, which, on several occasions when you have been employed on large and difficult matters, has reaped much benefit from the great abilities which you have been able to place at its disposal; and in mentioning this, I have been especially glad to record that, notwithstanding the many calls upon your time, you have never permitted your other avocations to interfere with your Post Office work, which has been faithfully and indeed energetically performed. There was a touch of irony in this word "energetically," but still it did not displease me. In accepting your resignation, which he does with much regret, the Duke of Montrose desires me to convey to you his own sense of the value of your services, and to state how alive he is to the loss which will be sustained by the department in which you have long been an ornament, and where your place will with difficulty be replaced.
