3,500 sqm had been surveyed by 8 December 1874, and 4,700 by 30 June 1875. The survey was suspended for 15 months following an incident in July 1875 when its members were attacked near Safad by a group of Algerians. Kitchener returned to the region, completing the remainder of the survey between 27 February 1877 and 27 September, with a total surveyed area of 6,040 sqm.[15]
