 Ipswich Bay. I have counted over two hmi- 

 dred gannets, all busily engaged in fishing, 

 which with them is a lively and not a con-

 a height of from thirty to a hundred feet, often 

 rising just before the plunge. At the plunge

 is great, and the wings are closed just before 

 the bird enters the water, which spurts up to 

 a height of five feet or more. After the waters
