BOOKS AND MAPS— The whole area is included in Sheets 52 (Ripon) and 
62 (Harrogate) of the one inch ordnance map, which maybe had geologically coloured. 
The Circular of the 90th Meeting (Brafferton, May i8th, 1891), and the report 
of the Excursion published in "The Naturalist," August, 1891, pp. 233-240 con- 
tain a good deal of information in all branches of Natural History. See also 
Baker's " North Yorkshire," Nelson's " Birds of Yorkshire," etc. Copies of 90th 
Circular can be obtained from the Secretary, price 2d. each. 
THE DISTRICT to be investigated is the only portion of North West 
Yorkshire which comes within the low lying area of the Plain of York and lies 
between the rivers Swale and Yore near their confluence, and it is requested that 
members will confine their investigation to the country lying south and west of the 
Swale and north and east of the Yore. 
The district is mainly agricultural land, with but few plantations or woods, 
but the ditches, streams, and ponds, as well as the two rivers themselves, should be 
carefully investigated for aquatic forms of life. 
In the northern portion, Baldersby Park and Woods offer scope for searching 
for woodland species, and in the extreme south, close to the confluence of the rivers 
on Ellingthorpe Ings, is the battlefield of Myton, fought 1319, called the " White 
Battle," or the "Chapter of Myton," from the large number of ecclesiastics who 
took part in it on the English side. 
As a whole, the district is one which has been very little investigated, even by 
the Ripon naturalists, to whom it is so readily accessible. 
ROUTES. — Members will leave Brafferton Station on the arrival of the 10-36. 
The general body of naturalists will investigate Leckby Carr and the neighbourhood, 
returning along the banks of the Swale. The vertebrate zoology section will pro- 
ceed to Baldersby Park. The geologists will examine the sections mentioned in 
Mr. T. C. Mitchell's notes. A conchological and general naturalists' party will 
walk from Boro'bridge to Brafferton, working the ditches and plantations alongside 
the Yore and Swale rivers, under the guidance of the officers of the conchological 
section. This route is outside (south of) the map given herewith.
