The work is expected to be so far advanced as to permit of material reductions in the present staffs at the following dates: in the Bronx, December 1911; in Queens, April 1915; in Brooklyn, April 1913; in Richmond, June 1911.

A detailed analysis of the cost of the work in the Borough of Queens, dated October 14, 1910, is subjoined:

	Cost per acre to date		Estimated cost per acre of completed work
Topographical Survey including preparation of maps of street system and grades
	Field	$ 8.13	Field	$ 8.06
	Office	$ 2.23	Office	$ 2.23
	Total	$10.36*	Total	$10.29
Monumenting, including final traversing and preparation of final map sections
	Field	$27.92	Field	$20.44
	Office	$10.89	Office	$ 7.89
	Total	$38.81	Total	$28.33

*The difference between the cost per acre to date and the estimated cost per acre of completed work is due to the initial cost of organization and to the cost of general work such as triangulation and traversing, which must be done at the start for the whole or most of the area to be surveyed.
