Each Plate was printed with the same header: PLATE __. TRANS. AM. SOC. CIV. ENGRS. VOL. LXVIII, No. 1154. LAVIS ON PENNSYLVANIA R.R. TUNNELS: BERGEN HILL TUNNELS. These headers were omitted for the e-text. Captions beginning in “K” with a number were printed directly on the photograph; some readings are uncertain and are indicated by question marks (?). In the tables of Figures 1-4, variation between “to” and “-”, and formatting of table entries, is as in the original. [Fig. 1, table] Per cubic yard, whole tunnel section: 3-33 _may be error for “3-3.3”_ [Fig. 1, last line of table] Total Pounds _text reads “Pound”_ Figs. 3 and 4, and Plate XXIV _apparent error for “Figs. 3 and 4, Plate XXIV” (usual form)_ [Figure 15 A, B, C...] _letters other than “B” do not appear in the printed Figure_ [Figure 15, caption] DETAILS OF “WEASEL” _quotation marks look hand-written, but printed text has spaces_ [Figure 15, “Index” (small table)] Multi-Duct Mandrel _text reads “Mult-Duct”_ which would be satisfactory to the engineers _text reads “satifactory”_ Missing or superfluous punctuation was silently corrected.
