GANNETS ON THE COAST OF CANADA 311 



flight were unsuccessful. Bonaventure is very precipitous 

 on its north and east sides, with chfEs 250 feet in height. 

 Its Gannets have, therefore, been tolerably secure from 

 molestation, but Mr. Lucas doubts if their numbers were 

 comparable to those on Bird Rock in its palmy days.* 



Extinct Canadian Gannetries. Perce Rock. — From 

 Professor A. E. Verrill, to whose assistance I am indebted, 

 we learn that Gannets were breeding as recently as 1861 

 in large numbers on Perce Rock,t which he describes as 

 perpendicular on all sides, and not to be ascended by any 

 ordinary means. Perce Rock is close to the mainland, and 

 a few miles only from Bonaventure ; there is a good plate of 

 it in Chapman's " Bird .Studies, "| but nothing is said about 

 Gannets there, nor did Mr. Brewster find any in 1881. 

 Great Manan Island. — Great Manan Gannet Rock is in 

 Fundy Bay. In 1859 Mr. Verrill and Dr. Brewer visited 

 this Gannet Rock and found only one or two pairs of 

 Gannets nesting, but they were told there had been more 

 before the building of the lighthouse. From this site 

 persecution soon drove them away, although it was probably 

 not entirely deserted until about 1866. At any rate, there 

 were no Gannets left in 1873,§ and this is all the hght, as far
