The depth of the wash is here 158 feet below theriver Team. A borehole to the east of Lamesley Church, put down by Mr. W. W. 74 Burdon, through the instrumentality of Mr. W. Barkus, Junr., provedthe Wash and subsequent deposit here to be 166| feet (see wood cut below).. LINE P2:Sand a. Yard-Coal Seam,h. Bensham do. c. Five-quarter Seam. d. Low-Main, or Hutton-Coal Seam. Plate XI., No. 4, Cross Section.—This section extending* from theTeam Colliery Betty Pit, and diverging slightly from a direct line inorder to take in the Bewicke-main Pit (recently sunk to the Hutton-seam)and terminating at Kibblesworth Colliery, shows the same dip dyke to thewest (here of seven fathoms) as that abovenamed. On the entrance tothe edge of the Wash a borehole from the surface proved the thicknessof the deposit to be 85 feet; but its total thickness determined by thewest line of the Hutton-seam workings being denuded near the Teamrivulet proved it to be 161 feet. As a large portion of the Team royalty in the Hutton-seam, or Low-main of the Tyne, lay to the west of the Wash, it was of importancethat a passage should be made through it, and the line of section givenwas the point at which this was accomplished. The first difficulty metwith was the dip dyke
