They ran across the shining sand, the Pacific thundering its long surge at their backs, and when they gained the roadway leaped upon bicycles and dived at faster pace into the green avenues of the park. There were three of them, three boys, in as many bright-colored sweaters, and they "scorched" along the cycle-path as dangerously near the speed-limit as is the custom of boys in bright-colored sweaters to go. They may have exceeded the speed-limit. A mounted park policeman thought so, but was not sure, and contented himself with cautioning them as they flashed by. They acknowledged the warning promptly, and on the next turn of the path as promptly forgot it, which is also a custom of boys in bright-colored sweaters.
