Itwas reported that on the morning of the26th the end wall of the mill was ob-servably out of plumb. At that time theconcrete was generally so hot that onecould not stand putting his hand on it out-side of the building. Later on, this par-ticular wall drew back again to the per-pendicular. The crack at the pier, crackA-7, (Fig. 2) shows the effect of thismovement on the outside wall, where the Magazine of Canada 327 -->^. ^^ _v>J .f 9-ZI >Tf-^. 328 The Pulp and Paper size of the wall beam i-haugos due to tlif-fereut spacing of the columus. The cracksabove and below the bracket of the columnalso seemed to indicate the longitudinalmovement of the floor. The cracking of the columns at theside of the building seemed to indicate thesame sort of expansion. These cracks oc-curred at both top and bottom of some ofthe columns. The top cracks are shownin Fig. 2. It will be noticed (Fig. 1), that in thesection of the floor at the wall end of thebuilding (right end), the main cracks runlongitudinally and are clearly marked andthat the cracks at right angles to the build-ing are comparatively few. Where the floor span decreases next tothe large girders which support the papermachine the cracks begin to run at rightangles, and end with diagonal crackswhich die away into the part of the floorwhich was not heated. It is suggested thatthe cracks at the wall end of the buildingwhich are parallel to the main girder oc-cu
