Lumber is to be thor-oughly kiln dried, having maximum moisture of 5 per cent,tongued and grooved and with a 5-in. face. The design? arc illustrated in Figs. I to 10 ted States Standard Cars The following specifications apply only to the 40-ton steelunderframe double sheathed box car: Framing.—All dimension framing to be yellow pine,square edge and sound grade, or fir of sections shown ondrawings. Side Sheathing.—To be long leaf yellow pine, B and bet-ter, or No. 2 clear and better fir 13/16 in. thick, tongued There are certain details in tlie construction of the bodiesof the double-sheathed and single-sheathed cars which arethe same in both. In many cases the same steel pressingsand commercial shapes are common to both t}-pes of brief description of tlie construction of these cars follows:Forty-Ton Double Sheathed Car.—This design hasan estimated weight of 44,000 lb.
