Generous Robin! Few, if any, of his Merry Men guessed how short he went of every other luxury in order to provide these tasty little feasts in the shade of the Forest trees. Other boys had hobbies—stamp-collecting, photography, painting—but Robin had none. For a hobby that needed pocket-money could not live beside such hospitality as Robin gave to his Merry Men. He let them assume that most of the grub came in hampers from home—some of it certainly did, but for the greater proportion Robin quietly paid at the Moston stores.

On logs tugged long ago to this particular spot, they sat in a rough semi-circle round the fire, and fell to with hearty good will. Some supplemented the viands from paper-bags held in reserve, and it seemed a thousand pities that such a jovial little picnic was doomed to be interrupted when the merriment was at its height. But interrupted it was, and in a manner that was both startling and odious.

Suddenly—even more suddenly than showers come in April—there splashed into the fire two jets of liquid, followed immediately by another and yet another.

The fluid drenched the logs and sent up clouds of pungent smoke, making their eyes smart and setting them coughing and sneezing. Simultaneously there was the unmistakable clink of syringes against tin pails, followed by smothered laughter and scampering feet.

With angry cries the Merry Men jumped from their logs and made away from the reeking fire. The fumes had a strong suggestion of acid from the laboratory, making the vicinity of the fire an unhealthy place to stay in.

"Those caddish Squirms!" yelled Robin. "After them, my Merry Men, after them!"

Yes, Robin—a long way after them! Those quick-heeled Squirms have made the most of their start, and, run you never so fast in pursuit, you will not catch them, not even be sharp enough to see the direction they took. They have vanished mysteriously and your vengeance must wait until another day.

"Marry come up, but they shall pay for this!" cried Robin, shaking his fist furiously into space. "Ere this week has gone by there shall not be a bone in the bodies of the Squirms that shall not ache, and ache again, from the cudgelling we shall give them. Are ye agreed on it, my Merry Men?"

"Ay, ay, Robin!" they cried, with deep and passionate sincerity.
