I have only a common edition, and I want a rare one. Thank you,” he added, as Tom handed him his hat and coat from the rack.

“Going out? This cold day! You forgot you were to sign some checks for the grocer and butcher.”

“I thought I made out those checks.”

“No; they were for the milkman and the coal dealer.”

“Well, I suppose I must make them out.”
