taken place, these still possess attractions for the naturalist. I 
would also mention those special matters which require more 
careful working out. 
In the Marsh and Middle Marsh is included the whole of the 
low-lying plain between the foot of the chalk wolds and the sea, 
including the sea-coast itself and all its wide attractions.. The 
chief interest of this district rests in its ornithology—more par- 
ticularly in the spring and autumn—and in connection with the 
migration of birds. The total number of species which can 
fairly be admitted at the present time into the Lincolnshire avi- 
fauna is somewhat doubtful. In the Humber district up to this 
date I have been able to record 290. This compares favourably 
with the Norfolk list of 293, and Yorkshire with 310. With our 
present knowledge as to the frequency with which rare birds 
turn up during the period of migration, far out of their ordinary 
route, I think we should attach very little importance to the 
increase of any local or county list by the addition of mere 
wanderers. ‘The record of such is interesting as showing how far 
some birds get driven out of their normal course. ‘The chief 
additions to the Humber district in late years have come from 
Spurn, but there is no reason why equally good results should 
not be obtained from our own coast. 
The flora of the marshes and the sea-coast is a very attractive 
and interesting one, and our knowledge of the same, as well as 
of Lincolnshire botany generally, has been greatly increased by 
the researches of the Rev. W. Towler, of Liversedge; Dr. I’. 
Arnold Lees, of Harrogate; the Rev. Adrian Woodruffe-Peacock ; 
Mr. F. M. Burton; Mr. O. Thimbleby, of Spilsby, and others. 
The collection of facts in connection with this district 
commenced as far back as 15g0, and the great naturalists of for- 
mer days—Gerarde, Ray, Dr. Martin Lister, and Sir Joseph 
Banks—have each in turn visited and investigated its floral 
treasures. > 
Before leaving this portion of the county I should like to call 
attention to the marine mammalia, the seals, and various forms 
of whale, grampus, porpoise, and dolphin. Although in recent 
years considerable additions have been made to our local list,
