(Frost and fire : natural engines, tool-marks and chips : with sketches taken at home and abroad by a traveller)
A two-volume geological travel treatise by J. F. Campbell, published in Edinburgh in 1864, arguing that frost, ice and heat act as natural engines, and written for educated general readers from the author's own field sketches. The figures are numbered wood-engraved line diagrams of cliffs, glacier sections and rock columns, built from contour hatching and stippled rubble, useful as geological section motifs and textural line fills.
