Dear Mr. Lighthall,
We had no chance to have anything like a talk on Saturday, for which I am sorry. My travelling companions had arranged things so that my time was altogether taken up; but I hope I may see you soon again here or in Montreal.
My most particular reason for writing this letter is that I noticed on Saturday that you were not looking well. You ought to take a holiday. You must have been working too hard. The people around one do not notice these things as quickly as a stranger, and one is often hardly conscious after a long season's labor how much one is in need of a rest and a little change.
We are much obliged to you for your courtesy to us during the short time you were with us on Saturday. Please give my best regards to Mr. & Mrs. Lighthall, and your brother and sister.
Yours very Sincerely
