AN ERUPTION OF TURQUOISE

S18,—The man who painted his tractor turquoise blue may not be as foolish as Miss Sparrow imagines. Bright colours arc more quickly picked out by on- coming traffic than are greys or fawns on country roads. I know a farmer who paints all his farm vehicles bright red for this reason.—YourS faithfully,
