. Canadian forest industries January-June 1912. Lumbering; Forests and forestry; Forest products; Wood-pulp industry; Wood-using industries. Fig. 5. Fig. 6 the blockings where the portions directly under the blockr»gUiuvc settled into the ground. A foundation of this kind is by all means better than none at all but is not a very mechanical arrangement. The load is all concentrated upon three points in each sill or foun- dation bearer instead of being distributed along its entire length as it should be. With 72,000 pounds of lumber on three bearers as shown by Fig. 2, there will be 72,000 9 = 8,000 pounds upon each blocking. Is it any wonder that they each and all settle into the soft top-soil and that the single 2-inch plank underneath the blockings is curved into an ox-bow? Care Must be Continuous And care and common sense should by no means stop when the foundation is ready, but should be carried through the entire oper- ation of piling, from the time the first board is placed upon the bear- ers until the rain roof is battened down and tied against the wind. One of the first mistakes usually made in piling lumber is shown at A, Fig. 3. The cross plank is placed just fair with the face of the bearing foundation. The next lengthwise plank is also faced with the bearer. Were this practice to be followed, the pile of lumber would slope backward instead of forward, as it should al- ways do. And the bringing of the front of the pile to the proper angle, after it has been started wrong, always leaves a bad looking angle in the front of the pile as shown between A and B. That last letter, B, marks another bad way of piling, it will be noted that the long plank projects farther front than the cross plank. This means that water will find its way along under the long plank, whereas had the long plank been flush with the cross plank underneath it as at D, and E, the water would nearly all run down over the cross plank instead of finding its way in between it and the long pla
