1. The Trigonometrical Survey of Palestine. By Lieut. 
Claude Eeignier Conder, RE. 
The survey which forms the subject of the present paper extends 
over an area of 6000 square miles, bounded by the Jordan on the 
east, the Mediterranean on the west, the river Leontes and the springs 
of Jordan near Dan on the north, and the desert of Beersheba on 
the south. Within these limits a complete triangulation, with two 
bases each about four miles long, has been extended, and the whole 
of the country mapped to the scale of one inch to the mile. The 
work occupied five years in the field, and nearly three years more 
in preparing the results for publication. 
The trigonometrical survey was first commenced in October 1871, 
when a party consisting of only four Europeans took the field. 
This expedition was sent out by the Palestine Exploration Fund, 
under the auspices of which society, Captain Warren, RE., had 
previously been employed in his adventurous explorations at 
Jerusalem during the years 1867 to 1870. 
The officer selected for the command of the survey party was 
Captain Stewart, RE., of the Ordnance Survey. Unfortunately the
