During the fiscal year ending June 30, 1907, there were 13,005,255 letters and parcels received at the dead letter office in Washington. Of these, 76,724 enclosed negotiable paper, money orders, etc., to the amount of $2,018,076.36. The currency alone found in dead letters amounted to $67,715.69. While many of these valuables can be returned to the senders, a great deal is lost thru carelessness in addressing.
