A, B, and C represent the three flaps or wings, which, with the upper flap D and the central rectangular piece or face E, form the envelope. In each of the parts A, B, and C a slot is cut, as shown in the drawing by c 0 0 to receive the tongue 61 of the flap D. In.v
the flap A the part a is cut so that it can be folded over to occupy the position represented by the dotted lines I).
The small flap a is to be folded inwardly on flap A, and flap A is then to be folded down on the central part E. The flaps B and C are then to be folded down and gummed to flap A and each other, the slots 0, c and a coming one over the other by the operation. The flap D is then to be gummed on its entire inner face, and the tongue (1 is to be gummed on both its inner and outer faces.
Fig. 2 represents the envelope folded, gummed, and ready for use, the upper flap D being open.
The envelope is closed, after lnoistening the gum on flap D and on both faces of the tongue d, by folding over the flap D and inserting the tongue (1 into the slots 0, 0, and 0 By this operationthe flap D is gummed to the flaps B and C, and the tongue d, after passing through the slots 0, c and 0 will lie between, and be CHARLES W.
