The Philosophical magazine; a journal of theoretical, experimental and applied physics . ossil trees in the accompanying section, whichit is my intention to describe, were exposed to view during thelast summer in the White Grit Quarry belonging to Mr. Lit-tler, at Scotch-row, near St. Helens. They were met with in re-moving the gray indurated silty clay, there known by the nameof warren, a deposit nearly similar to many coal-floors, forthe purpose of working the sandstone lying under it. Thesurface is covered with from six to eight feet of brownish co-loured till, under which the warren containing the fossil treesoccurs. This latter deposit was exposed about seven yardsin thickness, and the white grit lying under the workmen in-formed me was ten yards thick. The inclination of the stratais to the east at an angle of about 23°. All the trees were atright angles to the strata, and stood in a line nearly north andsouth, about eight feet six inches above the grit rock, and con-tinued upwards until cut off by the till. Section of Mr. Littlers Quarr^, near St. Helens. Note.—This imperfect sketch is intended to give the reader merely anidea of the position of the trees, and not to show their external characters.
