Thefirm is noted for having had a number of the leading men of the cityof Philadelphia connected with it. At no time, however, in its historyhave there been many interests. Even now as a corporation thestock is almost entirely owned by the officers and the directors. Both Mr. Morris and Mr. Tasker lived to be very old men, each of them reaching nearlya century of life, and theypassed away only a fewyears ago. Prominentamong the different own-ers were Henry Morris,Thomas T. Tasker, Jr.,A. G. Morris, WistarMorris and CharlesWheeler. For the past. lengths of pipe of different sizes and thicknesses of metal. Manu-facturing conditions change to a slight extent the theoretical sizesand weights of the different portions of the pole. This, however,does not interfere in any appreciable way with the strength rela-tively to the weight, and the cost is proportionally less. The modern pole of the most approved form consists of three ormore wrought iron tubes of different diameters. The sections aretelescoped one within the other far enough to obtain an ample sup-port, and the joint made perfect by swedging. The lower section isnot only the largest, but is of thicker metal. The thickness of themetal is, in the lighter poles, decided by the usage to which the poleis subjected in the way of accidents, collisions from vehicles,, it is strong enough for this purpose, it is amply thick forthe work put upon it by the strain of wires, etc. The re-maining sections are of such thickness as is found most eco-
