Gardening Box – Marking Out


Card number 3 in the Hamlyn Gardening Cards collection.
To mark out a right angle, drive in a peg at the corner and from this stretch a garden line to mark one side of the right angle. Drive in a peg against this line, exactly 3 ft. from the first peg. Attach a string 4 ft. long to the corner peg and another 5ft. long to the second peg. Draw them together to form a triangle and where they touch drive in a third peg. A line stretched between pegs 1 and 3 will be at right angles to the line between pegs 1 and 2. 

To mark an oval, use a line to mark out the full length of the oval and midway, another at right angles to mark the width. Drive in a peg at one end of this line. Attach to this peg a piece of string exactly half the length of the oval and draw it tight so that it touches the long line first on one side of the centre and then on the other side. Drive in a peg at each of these points. Measure the length from one of these pegs to the extreme end of the oval on the farther side. Make a loop of string exactly twice this length, throw it over the two pegs on the central line and pulling it taut, use a pointed stick to mark out the oval on the ground. 

To mark out a cirle, drive a peg into the centre. loop over it a string exactly half the width of the circle required and draw it around., fully extended with a pointed stick inside the loop to mark the ground.
