The Bobbsey Twins Keeping House by Laura Lee Hope

Waiting until some of the men had moved aside from the delivery window, / Bert made his way to it. Mr. Anderson knew the Bobbsey boy, for in the / summer Bert had often gone to his father's lumber office, and, more / than once, had been allowed to go down to the post-office for the mail.

"No letters for the lumber company to-day, Bert," the postmaster said, / with a smile. "There were a couple yesterday, but Mr. Jones got them."
