Glance frequently over the stack and see if the outside presents the appearance of an ellipse, and keep a sharp lookout for high and low spots, for they will throw the stack out of balance. If the middle is too full, the outside will slip out, and an undesirable job of propping will begin. Put in two-thirds of what is intended for the stack before commencing to draw in.
FIGURE FOUR.
Drive so as to leave a little space between load and stack. Don't let a stack stand over night at this stage if it can be avoided, (See figure 4) but put on the next two loads as quickly as possible, for the outside of the stack will settle rapidly.
FILLING THE MIDDLE.
FIGURE FIVE.
Lay a tier of bundles through the central part half the length of the stack, alternating heads and buts, then lay a course around with the heads lapping across the middle tier; now another tier through the center, and two courses around it; then another tier at center and courses around, until the center is three or four feet higher than the outside, depending on size of the stack, and the last course laid laps half way from head to band on the outside course of the stack. It will be seen that while building the main part of the stack, the courses were laid from outside to center, and while filling the middle or putting in the stuffing, the courses are laid from center towards outside. Now commence outside, lay a course, heads out, half way from band to but on outside course; in small stacks omit last instruction; then turn buts out, lap half and lay to center; then lay a course around outside, neither laying out or drawing in.
