Section 1.--ANCHORING.

=1. Rope pulley anchor=--a car which grips by sinking its wheels in the soil; employed for ploughing tackle.

=2. Anchor plate=--buried in the ground below a mass of masonry--for attaching guys, tie rods, &c. Sometimes a frame, or plate, laid on the ground and ballasted, is the method used.

=3. Screw mooring,= screwed into the ground.

=4. Heavy stone= sunk in the ground and having a ring attached; or a mass of concrete, similarly placed, used for guy ropes, tie rods, and foundation bolt attachments.

=5. Grapnel.=

=6. Mushroom anchor.=

=7. Double fluke anchor.=

=8. Martin’s patent anchor,= with swivelling flukes. Several other patent anchors are modifications of this.

Stakes, with or without flanges, vertical or horizontal, are sometimes
employed, the flanges taking the cross strain of the ties, &c. Fencing
posts, gate posts, tree stakes, and tennis poles are of this class.
