lars runs a network of thirteen rolled wrought-iron 

 beams, made by Cooper, Hewitt & Co. of Trenton, 

 N. J., four of them being fifteen inches thick and 

 weighing one hundred and fifty pounds to the yard, 

 nine nine inches thick, weighing eighty-five pounds to 

 the yard, running above and crosswise with the heavier
