This negative result is probably explainable by the lack of variety in the several traverses considered. It serves to demonstrate, however, that for the dip spac- ing used in the work analyzed, the spacing exercised little if any effect on the amount of misclosure. Considering also the surprisingly small size of the probable angular misclosure obtained, this result suggests that no closer spacing is necessary, and indeed, that an even wider spread than the average one used might be practicable. The average spread on the traverses studied from the shot point to the middle geophone was 1,700 feet. 650
