The rovers are invariably artistic. Men and women, and I have met both, they always possess the gift of expression. They are musicians, singers, and can spontaneously dramatise a situation or a story. Some of them are clever draughtsmen and can dash off a pencil portrait of an onlooker with a sureness of line that is amazing. Their tastes are not expensive, they can be as charming and as content in a shelter as in a restaurant or studio. The one thing they cannot and do not bear is any measure of routine.
