Below this was a base of concrete, about 10 feet by 10 feet, and visibly 12 iuehes in thickness. The soil is a dead loam sand, with mica indications, showing it to be not far from quicksand, if saturated with water. This character of bottom extends down to some 21 feet helow curb line where a better quality of sand is met with. The upper sand wheu saturated with water renders it very uucertaiu and unreliable for up¬ holding a great weight with stability. The position of the elevator indicates that the place where mnch water was used ou the floors in mixing up mortar was near the liue of coluunis which fell, and customaryin such operations water continuously overflows aud drips down to the ground. Directly underneath one corner of the concrete base is an 8-inch bi-ick circular wall of an oUl cistern, and thus the foundation for the basement column rested partly npou this wall and the brick tloov of the cistern, and partly upon the soft ground. The ruins show the iron column buried for more than 7 feet of its length down through the foundation, the iron plate and the stone hlock being eaCh shattered into four parts. The broken foundation has not beeu disturbed, as the Coroner decided to have his jury first view it in its present condition. Afterwards the pieces will be removed and au examination made of the condition of things underneath the concrete. Apparently the cause of the disaster ia to be found in the inadequate fouudatiou under the basement column, and many facts substantiate the theory that this columu sank aud with it followed the line of columus above, together with the floors, all dropping at one aud tho same time in funnel shape. On the flcors around this liue of columus there had been placed far greater weight thau elsewhere iu the building. Near tho
