HEADQUARTERS.— The Headquarters will be at Sleights Hall, about 
half a mile up hill from Sleights Station. The accommodation is ample if 
applied for in time, but is quickly absorbed in the holiday season. Single beds in 
bungalow in garden if preferred. Terms— Bed, Breakfast, Sandwiches, and late 
Dinner, G/- per day. Application should be made at once to 
Mrs. Rennison, The Hall, Sleights, S.O., Yorks , 
who will procure beds outside if the Hall is full. 
DISTRICT.— The Esk Valley from Whitby to Glaisdale is extremely 
picturesciue. The lower ground is well sheltered and wooded. The Moors on the 
Whitby-Pickering Road are within one mile of Headquarters, within which 
distance there is a rise of 500 feet. All sections are likely to find this district 
favourable for investigation. 
ROUTES- — On Saturday all parties will await the arrival at Sleights of 
the 10-21 a.m. train from Whitby, and will travel by the same train to Egton, 
walk from Egton through Arncliffe Woods to Glaisdale, and up part of Glais- 
dale. All will assemble at the Institute, Glaisdale, at 4 p.m., where the Glais- 
dale friends have kindly intimated a desire to offer a welcome and Afternoon Tea. 
The Divisional Secretary will be glad of a post card from members who expect 
to be present. Train, Glaisdale to Sleights, 6-8 p.m. 
On Monday — Iburndale and Little Beck, or Wliitby Coast or Aislaby. To 
be fixed by members present, not leaving Headquarters before 9-30 a.m. Word 
will be left at the Station as to route adopted. 
PERMISSION to visit their estates has kindly been granted by the fol- 
lowing gentlemen : — For Glaisdale, Edwin Harry Davis, Esq., J. P. For Egton 
and Arncliffe, Kenneth Foster, Esq., J. P., but members must keep to the paths. 
Permission is also kindly granted to visit the grounds at Egton Lodge. For Little 
Beck, E. C. Brooksbank, Esq. No plants must be removed. Members, when 
traversing Mr. Brooksbank's estate, are also requested to keep together as much 
as possible. 
GEOLOGY. — The Geological Section will be officially represented by 
one of its Secretaries, Mr. John I-Iolmes, and by Mr. J.J. Burton. 
Mr. J.J. Burton writes : — The physical features and the solid geology of the 
Glaisdale district are full of x'ariety and interest. The river Esk, which rises in 
the Cleveland moorlands to the West and pursues an eastward course, mostly 
through a deep narrow valley, is remarkable for its sinuous curves, elbow bends 
and S loops until it empties itself into the sea at Whitby. On its northern banks 
there is no lateral \ alley of any importance, and the streams feeding it are for the 
most part short and insignificant, merely bringing down the rainfall of the valley 
slope. On the south side, however, besides the Gorge of Newton Dale there are 
many valleys which have been cut deep down into the moorland plain at right 
angles to the Esk and end abruptly in a combe-like cirque at the head of each 
dale. The streams in these short lateral \ alleys are rapid, copious and sometimes 
turbulent. The one notable exception to the general character is the Murk Esk 
and its tributaries, which bring down the drainage of the water shed about 1,400 
feet above sea level dividing the Esk from the Rye systems. Except in length 
the Murk Esk is probably the more important stream. The two streams unite at 
Grosmont. 
It is to the cutting out of these narrow valleys to the south that we owe so 
much of the picturesqueness of the district chosen for investigation. The glacia- 
tion of the area has been very fully investigated by Professor P. Kendall, and 
his remarkable contribution to the solution of many difficulties read before the 
Geological Society should be referred to prior to the meeting. It may, however, 
be mentioned here that the Esk Valley has been ice-blocked, and its pre-glaciai 
f^oor is much below the present river bed. On the recession of the ice the 
amount of drift left has in several cases diverted the course of the stream, and in 
the case of Crockley gill, and again near Egton, caused it to cut out fresh 
channnels in the solid rock.
