(Fig. 14) shows the con- struction and use of a spreading board. Two pieces of pine, fasten- ed together by cleats at the end, are left wide enough apart to admit the body of the insect. Narrow strips of cork are then tacked on the under side of the pine strips so as to form a bottom to the groove and to serve as a support for the pin upon which the insect is placed. Another broad strip is nailed to the cleats and forms the base of the spreading-board. Of course tlie insects must be pinned to the spreading-board before they have time to become brittle, and w^hile they are in a relaxed condition. It will require some patience and skill to spread the wings of the smaller moths without injuring them, but practice will make Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Ontario.
