Dear Mr.Pike，
I very much regret I was unable to attend school this morning owing to a severe attack of illness. I am enclosing here with a certificate from the doctor who is attending me, as he fears it will be several days before I shall be able to resume my study. I trust my enforced absence will not give you any serious inconvenience.

I have done all my things here. I sincerely thank you for the trouble you have taken for my sake. I am leaving for home by train at two this afternoon. This is to say good-bye to you. Please kindly remember me to your wife.
