40 THE SWAN AND HER CREW. 



cabin. Frank could not leave the helm, and yet could not 

 stay where he was ; so without further thought he plunged into 

 the water at the stern of the yacht, and, holding on by the 

 rudder, he contrived to keep her on her course until Jimmy 

 reappeared with something thrown over him, and took hold of 

 the tiller. When they came to an anchorage in a secluded spot 

 among the reeds, they bathed and dressed. 



" Well," said Dick, " if we go on having adventures at this 

 rate, we shall have plenty to tell when we get home." 



" E like adventures, but these are not the sort I like," said 

 Jimmy. 



" Well, never mind, better luck next time," said Frank, 

 soothingly. 



Sailing through Kendal Dyke, which in places was so narrow 

 that the Swan brushed the reeds on both sides as she passed 

 through, they reached the Hundred Stream, and, turning to the 

 south-westward, they sailed, with no further adventure, until 

 they came to Heigham Bridge, where they had to lower their 

 masts in order to get through. While Frank and Jimmy did 

 this, Dick took his butterfly net, and went after an orange-tip 

 butterfly, which he saw flying past. This butterfly is one of 

 the first which makes its appearance in the 

 spring, and it is one of the prettiest. It looks 

 as if a bunch of red and white rose petals 

 had taken to themselves wings and fled. It 

 is a small butterfly, having an orange- red tip 

 on the ends of Its forewings. The male only

 greyish black tip. The under surface of the 

 wings of this pretty insect is no less beautiful than the upper. 

 It is white, with bright green marblings, or what appear as 

 bright green -to the naked eye. When looked at through the 

 microscope it will be found that the green appearance is caused 

 by the mixture of black and bright-yellow scales. (I suppose 

 that most of my boy readers will know that the dust which is 

 so easily rubbed off a butterfly's wings is in reality a coating of 

 scales arranged one over the other like feathers, and of very 

 exquisite shapes.) The caterpillar of the orange-tip is green, 

 with a white stripe on each side, and the chrysalis is very 

 peculiar in shape, tooth-like, and pointed at both ends. 



Dick was a long time away ; and when he came back, flushed
