in the concrete wall of the building, while the other end rested on a bracket, about four inches wide, placed on the side of the columns, to which, after all pipes, etc., were installed, it was to be permanently bolted and riveted.
After the bridge company had placed all the floor beams in position, and, according to the evidence produced by the defendant, had bolted all of them to the brackets, the work of that company was temporarily suspended in the winter of 1917-1918, and was not completed until some time after the accident hereinafter referred to.
In the spring of 1919 the steel company notified the Yariety Company that it was ready for it to proceed with its work of installing the gas main, and accordingly the Yariety Company sent a number of its employees, one of whom was Harry Alies, to perform its contract. The gas main was a large iron pipe, about four and a half feet in diameter, and had been shipped to the defendant’s building in sections from thirty to forty feet long, which weighed about three and a half tons. In order to get these sections of the main into the basement of the building, where, as we have said, the main was to be installed, the Yariety Company, with the permission of the defendant, moved four of the floor or I-beams located about the center of the building, and by means of an electric crane belonging to the defendant, located in the top of the building about twenty-five feet above the floor beams, lifted the sections into the building and lowered, them into' the cellar or basement. After the sections of the main had been placed in the basement, the floor beams that had been removed for that purpose were replaced and rebolted by the employees of the Yariety Company, and they then proceeded to distribute the sections of the main in each direction. This was also' accomplished by the use of the electric crane, to which was attached a cable, with a hook on the lower end of it. A “sling” was placed around the section of the main to be moved, and then carried up between the floor beams and connected with the hook on the cable. The floor beams were from five to ten feet
