Ten minutes later I entered the shop of an athletic outfitter. Unfortunately he had no white vests with red edges: I had to purchase one with blue. A scarf or towel I could find at home.

Then I entered a tobacconist's.

Four days later I had collected Scarf or Towel Exercises 2 and 3.

"We can," I said, "now make a start." As a matter of fact it was not altogether a foolish proceeding. Deep thinkers are apt to overlook the need for physical culture. This error I decided to remedy.

Every morning I (1) stood in position illustrated, (2) raised arms above head in manner indicated by the instructions, (3) straightened right arm and lowered right hand so that towel (still taut) sloped to right, (4) returned to Position 1. I then changed towel for scarf (my own idea) and continued with Exercises 3 and 4.

I was very happy; my only worry was the absence of Scarf or Towel Exercises 1.

Every morning I called at the tobacconist's and purchased packets of cigarettes, eagerly searching them for the missing card. Every afternoon I called again.

For a week I bore my disappointment bravely; then I became cynical.

"Perhaps," I said, "there is no Exercise 1. It may be a joke on the part of the makers."

My consumption of cigarettes increased. Packet followed packet with extraordinary rapidity, and still no Exercise 1.
