and it was not until the middle of May 1949 that a complete four-man party
and a computer-—draftsman was available, In the interim, the department
head alternated as chief of party and computer-draftsman, By late fall
of 1949, two full parties were available and a third was on requisition.
Later, additional personnel were requisitioned, until the department at
maximm consisted of a department head, two senior engineers in charge of
forces at Engebi and Biijiri, two computers, one draftsman, and twentyfour field men operating as six or seven parties as required.

EQUIPMENT AND SUPPLIES
Early in the Project, some difficulties were experienced with
equipment because at times it was necessary to substitute makes other
than those ordered, and because often, as with plumb bob points and red
targets, these pieces of equipment were not interchangeable. Later these
difficulties were avoided by the inclusion of instructions on requisitions, prohibiting substitutions.
