He is suffering from a kind of hay fever, which is perplexing but not dangerous. He had thought Sister St. John McMaster, D.C. was in retreat, but she was not. Frank Maurice Francis Egan left two weeks ago on his vacation, and McMaster encloses here a characteristic, undated evaporation from him. He thinks he misses John more than his father does, but he does not; besides, he has his own baby to think of. McMaster does not know if this letter will reach John. It goes by the steamer Ben Vento, which is chartered for this trip by John Rosche ?. If is should reach him before he leaves Rio de Janiero, he should note the following instructions carefully. 1 Put Brazilian postage stamps on his letters, 2 watch for steamers from Rio to New York, and send a few lines by every possible mail. 3 McMaster includes a letter which may be useful to John in case he is ill. It assures Captain McLean of the Bark Templar that such expense as may be incurred will be refunded on presentation of the letter to McMaster, C. Morton Stewart, or John D. Keiley. John should show this letter sheet 3. to Captain McLean now. It gave McMaster great solicitude to read that yellow fever and small pox were prevalent in Rio in June. He urges John to say earnest prayers, and assures him many are being said for him. He is so dizzy that he cannot go on writing more. A.L.S. 5pp. 12mo.
