In less than a quarter of an hour their approach was signalled by the enemy's vedettes to the forts ashore, which promptly opened fire. Mr. Adams, having towed the catamaran within its proper range, with his own hand pulled the plug releasing the clockwork, and gave the order to cast off, leaving wind and tide to do the rest; which they doubtless would have done had not a gun from one of the French batteries plumped a shot accurately into the catamaran.

The catamaran exploded with a terrific report, and the wave of the explosion caught the retreating boat, lifted her seven feet, capsized her, and brought her accurately down, bottom upwards.

A score of boats put out to the rescue, picked up the exhausted swimmers, and attempted to right and recover the boat, but abandoned this attempt on the approach of an overwhelming force of French.

These, coming up, seized on the boat and gallantly, under a short-dropping fire from our squadron, proceeded to right their prize; and, righting her, discovered Major Hymen, clinging to a thwart, trapped as an earwig is trapped beneath an inverted flower-pot.

MISSING!

Miss Marty had just finished watering her sweet-peas and mignonette; had inspected each of the four standard roses beside the front gate in search of green-fly; had caught a snail sallying forth to dine late upon her larkspurs, and called to Cai Tamblyn to destroy it; had, in short, performed all her ritual for the cool of the day; and was removing her gardening gloves when a vehement knocking agitated the front door, and Scipio hurried to announce that a caller—a Mr. Basket—desired to see her on important business.

"Mr. Basket?" she echoed apprehensively, and made at once for the parlour, where she found her visitor mopping his brow. Despite the heat, he was pale. In his left hand he held a letter.

"You will pardon me," he began in a flutter. "Am I addressing Miss Martha Hymen?"
