The use of steel casings for the model bomb experiments enabled the adoption of a magnetic method for separating fragments from the medium in which they were collected. A search was made for the best material which could stop fragments, without greatly changing their appearance, and from which they could readily be recovered. A circular pit was designed to withstand the bomb explosion. Fragments were then collected and examined. Halftone illustrations of the pit and fragments are included.
