"My dear, of course. The Complete Letter-writer, by J. P. Smith. Chapter V—'Stiff Notes to Landlords'—shows Mr. Smith at his best. 'Gossipy Budgets, and should they be crossed?'—see Chapter VI. Bless you, I can write to anybody."

"This is to a man you've never met. He's a private at the Front and his name is Mackinnon."

"'Dear Mr. Mackinnon'—that's how I should begin. Do we want to say anything particular, or are we just trying the new notepaper?"

Mrs. Jeremy put down her work and gave herself up to explanation. Private Mackinnon was in a school friend's husband's regiment, and he never got any letters or parcels from anybody, and the friend's husband had asked his wife to ask her friends——

"Wait a bit," said Jeremy. "We shall want the College of Heralds in this directly." He took out his pencil and drew up a pedigree:—

"There you are. Now you think it's J. P. S.'s turn to write to Mackinnon." He drew a line from one to the other. "Very well; I shall tell him about the old school."

"You do see, don't you?" said Mrs. Jeremy. "All the others get letters and things from their friends, and poor Mr. Mackinnon gets nothing. Katharine wants to get up a surprise for him, and she's asking half-a-dozen of her friends to send him things and write him jolly letters." She picked up the muffler she had been knitting. "This is for him, and I said you'd do the letter. You write such jolly ones."

Jeremy threw away the end of his cigar and got up.

"Yes, but what about?" he said, running his hand through his hair. "This is going to be very difficult."
