surface and about 10 feet distant. The wings were used quite 

 rapidly and were approximately half opened, as nearly as he 

 could determine. Both wings and feet were used. The wings 

 and feet appeared to co-ordinate, and made the back-stroke in 

 unison. 



Mr. Bertram S. Griffin, Haverhill, Massachusetts, notes that 

 in July, 1900, one of his friends saw a Loon using its wings 

 under water at Bear Pond, South Waterford, Maine. The 

 wings were half spread and used in quick strokes and with the 

 feet. His friend has observed this on several occasions. 



Mr. Arthur W. Beckford, Danvers, Massachusetts, writes 

 that he saw a Loon swimming under water in a narrow salt- 

 water stream, and using its wings when followed by a power 

 boat. Quick, short strokes were employed, but he believes that 

 the wings were used more for the purpose of turning than for 

 progression. The feet also were utilized, but he was unable to 

 tell whether both feet and wings were used together. 



Mr. Arthur L. Clark, Ithaca, New York, says that in June, 

 1911, at White's bridge, which crosses a narrow strip of water 

 at the south end of Sebago Lake, Maine, he saw a Loon 

 swimming four or five feet below the surface and against the 

 current. 



The wings were not fully spread, but were taking about half-strokes 

 or less, i.e., short, steady strokes. The wing-beats could not be called 

 quick, but rather about normal for a Loon. The feet were not seen. 



Mr. Charles K. Averill, Bridgeport, Connecticut, says that 

 as he sat on a rock on the shore of a small lake in the Adi- 

 rondacks a Loon passed near under the surface of the water. 

 The wings were spread, but not so widely as in flight. They 

 were used with a motion "much slower than when flying and 

 with not so extensive a sweep." 



Dr. William C. Braislin, Brooklyn, New York, says that he 

 saw a wounded Loon in shallow water in Great South Bay, 

 Long Island. The wings were spread to less than half their ex- 

 tent, he thought, and in locomotion were quickly jerked against 

 the sides again. They were used to supplement the feet in 

 swimming. The feet, he assumes, were the chief means of 

 locomotion, but doubtless were greatly aided by the wings,
