Hemlock and white pine are the principal lath woods in Pennsylvania, although spruce, yellow poplar, cucumber, and aspen were also reported. SHINGLES. Chestnut, because it is a durable wood outside and cheap, is the principal shingle material in Pennsylvania. White pine, hemlock, and a few hard- woods in small amounts were the other woods to contribute to the output. In the production of shingles Pennsylvania is not one of the principal states, but compared with the quantity of wood used by the various wood-using in- dustries of the State and especially with the home-grown material reported, it is of considerable importance. Shingles made in Pennsylvania are both split and sawed, the sawed shingle is-more salable and therefore, the kind generally manufactured. Table b.—Production of Laths and Shingles. Laths, . Shingles, 78,758,000 26, COOPERAGE. Table "c" reports the quantity and cost of material used in Pennsylvania for the manufacture of barrel stock, staves, and heading. Raw material for both stave and heading is usually purchased in the form of bolts but consider- able sawmill waste is saved by being converted into these products. The prices given were not taken from the Census bulletin as they are not com- prised in these statistics. Information concerning them was collected from cooperage plants by agents when in the field in connection with the wood- using industry investigation, and an average made of them and applied to the Census figures. The manufacture of cooperage is an industry which rightfully comes within the scop
