FIELD MEETINGS, 1907. 
The first meeting of the year, and the Fifty-fourth Field 
Meeting of the Union was held on Whit Monday, May 2oth, at 
WELTON-BY-LINCOLN. Assembling at Lincoln, the party 
Was conveyed to Welton by waggonette, where the President 
~ Rev. A. Hunt, M.A., met them and conducted the members to 
Hackthorn, and by foot road and field as well as through gorse 
and coppice, gradually brought them to Welton where Mr. and 
Mrs. Hunt kindly provided High Tea. 
The day’s work was successful in many ways. ‘The Botany 
was well worked by Rev. E. A. Woodrulfe-Peacock and others. 
Mr. G. W. Mason led the Intomologists. Mr. W. Dennison 
Roebuck took charge of the Conchologists and with such leaders, 
and willing followers, the meetings are of such value as to obtain 
a great amount of information for the County lists for publication. 
‘The Geology was perhaps the most interesting feature. ‘The 
presence of Mr. H. Preston was indeed valuable, he always being 
ready to explain as far as possible what he knows on the subject. 
_ Mr. F. M. Burton prepared the following paper which was read at 
_ the close of the meeting.

Lincolnshire is, by glacial and alluvial drifts. I need scarcely 
remind you that our County is confined to the entire secondary, 
‘or mesozoic, division of rocks—from the ‘Triassic on the west to 
the cretaceous beds on the east. After passing the lassicclays on 
the west we come to limestone beds on the top of the Lincoln 
Cliff, and find in succession the Inferior Oolite group,—made up
