A Garden Guide - Extracting a Weed from a Lawn

Illustration by William Heath Robinson (1872-1944) showing a typically convoluted method of weeding a garden lawn. A man is hosted by ropes supported by a teepee configuration of poles worked by onlookers. He holds a corkscrew type instrument in his hand, in order to extract a single weed. Robinson was a regular contributor to the Sketch, the Bystander and other ILN titles during his lifetime. His weekly drawings featuring mind-boggling contraptions and designs were immensely popular.

Soil triangle diagram

Soil triangle diagram. This diagram is used to work out the type of soil in an area. A sample of soil is left to settle in water. Larger particles settle out of suspension faster than smaller ones. Soil particles are placed in three categories depending on their size: sand (largest), silt and clay (smallest). Once the layers have settled, the depth of the layer is used to work out its percentage as a component of the soil. The three percentages are then read off the axes of the triangle: clay horizontally, silt towards bottom left and sand towards top left. Loams are the best soils for cultivation
