Croton River was the only place I could find suitable to the purpose, all circumstances being taken into consideration. I wrote your Excellency what I had done, and where I was, that if you had any thing in charge I might receive your orders. I wrote you the reasons for my not waiting upon you in person were, I had many letters to answer, and many matters to regulate in my department, which prevented me from returning. Besides which, it was almost half a day's ride, the weather exceeding hot, and myself not a little fatigued. And here I must observe, that neither my constitution nor strength is equal to constant exercise.

Letter to George Washington (July 1778)
