Or, in the above case, a saving of approximately$2,000 in favor of the lighter woods. It must be remembered that the above example Fig. 5 (left)—well con-structed crate containing sixchairs. Considerable savingcould have been made ifpaper bags had been usedinstead of excelsior. Fig. 6 (right)—an exampleof bad practice.

If, how-ever, the problem is worked out, using your ownfigures you can readily determine the advisability ofcontinuing to use the lumber you are now using orchanging to a different species. The figures usedabove for the weights of different species of lumberare for air dried wood or, in other words, wood hav-ing a moisture content of from about 12 to 15 percent. The Use of Diagonal Braces The advisability of using diagonal braces is ap-parent to many shippers, yet there are countlessothers who, because they do not understand the ad-vantages of a diagonal as against the usual crossslat, still do not use them. A cross slat, or in otherwords the vertical or horizontal piece of wood nailedto two adjacent and parallel frame members, helpsbut little towards stiffening the crate, whereas adiagonal brace, or a stri
