^ The solid geology is of a simple type. The moors are capped with lower 
oolite. Those to the south form an east and west anticline with a sharp dip of 
the strata towards the Esk. The lowest beds in tlie area to be \ isited are a por- 
tion of the Lower Lias exposed near Grosmont, but there are many cliff sections 
of the Middle and Upper Lias, and also of the Estuarines. 
The cliff sections of the Lias at Whitby are too well known to need any des- 
cription here. 
BOTANY. — The Botanical Section will be officially represented. 
Flowering Plants* — Dr. W. G. Smith, B.Sc, writes : — Glaisdale, 
with its varietv of stream-side and valley slope woods leading up to wet and dry 
m.oorland, offers good opportunities for observing most of the representative 
plants of the dales and moors of North-East Yorkshire. A perusal of a number 
of lists from various parts of the district does not, however, reveal any very rare 
species. The slag heaps, although still rather bare, except for large patches of 
Epilobium an^ustijolium, might on careful examination reveal some alien or un- 
common species, Arncliffe Woods and their extension up Glaisdale form one of 
the largest areas of woodland in North-East Yorkshire. Oak is well repre- 
sented by Quercus sessiliflora, Q. Robur, and we have observed numerous inter- 
mediate forms. Most of the commoner woodland trees will be found in one part 
or another of the more natural woods or in the plantations. In examining the 
woods the Botanists will find that the ground vegetation coincides fairly closely 
with the degree of moisture. The upper slopes are dry and not too productive ; 
lower down, numerous springs emerge, and with them comes a more abundant 
flora ; here and there Alder thickets occupy a still wetter type of soil. 
Mosses and Hepatics. — Mr. W. Ingham, B.A., writes ;— Glaisdale 
is a very rich district for all the branches of Bryophytes. A few of interest only 
can be mentioned here. 
I. Sphagna , S. compactum var. imhricatum on Sleights Moor, 5. squarrosum 
var. spectabile, S. tuvfaceiim, and S. stibnitens var. virescens forma squarrosula in 
Arncliffe Wood and S. Girsens)hnu in Cronkley Gill. 
II. Tnie Mosses, Fissidens pusillus. Hetevocladium heteropteyum, Dicramm fus- 
cescens and Campylostelium saxicoli in Cronkley Gill, Dicranum pdvellum, Hypnum 
eiigvrium, Dichodontiiim flavescens, Hypnum ochraceum var. Uaccidum and the type 
fruiting which is very rare, and H. fliiitans group Amphibium var. atlanticum forma 
in Arncliffe Wood, the last /. tetiella, being the first so named by Renauld, 
and Campylopus atrovirens on Sleights Moor. 
III. Hepatics. Pellia Neesiana, male plant, Metzgeria conjugata, Aneura 
multifida, Aliciilaria compressa, Eucalyx paroictis (very fine), Haplozia sphaerocarpa, 
Liochlaena lanceolata, Lophozia incisa, L. biirbata, Lophocolea cuspidata, Harpan- 
thiis scntatus, Cephalozia Lammersiana var. servatiflora (known only here and in S. 
Lancashire), Blcpharostoma trichophyllum (in large pure patches on stone), Scapania 
nemorosa, S. dentata, S. intermedia, S. umbyosa, all in Arncliffe Wood, and S. curta 
on Sleights Moor. 
The very rare L. lanceolata also in Cronkley Gill. 
N.B. — The Cronkley Gill is about 3 miles from Glaisdale, and the Arncliffe 
Wood above is that end of it near Glaisdale. 
Fungi. — The Mycological Committee will be officially represented by Miss 
C. A. Cooper and Mr. A. E. Peck. For report of Fungus Foray held in Eskdale 
in September, 1902, see " The Naturalist " for that year, pp, 355 — 365. 
VERTEBRATE ZOOLOGY.— The Vertebrate Section will probably be 
officially represented. 
GONGHOLOGY.— This Section will probably be officially represented. 
ENTOMOLOGY.— The Entomological Section will be ofificially repre- 
sented by Mr. G. T. Porritt. 
Lepidoptera. — Mr. T, A. Lofthouse writes :— The district to be visited 
is one that has been very little worked by Lepidopterists, and should be produc- 
tive of many good species. Among Lepidoptera that I know to have been taken 
in the district are : — Thecla rubi, C. typhon, C. elpenoy, M. stellatayum , M . mundana, 
N .^plantaginis, H. sylvanus, H. velleda, B. rtibi, B. quercus, S. pavonia, A. menyan- 
thidis, C. haworthii, A. agathina, N. maura, 0. suspecta, C. xerampelina, A. occulta, 
H. glanca, P. iota. P. interyogationis. G. papilionayia, A. fumata, S. belgiayia, 
L. caesiata, Eup. pulchellata, H. ruberata, M. galiata, T. vibtirniana, P. bicostella. 
Neuroptera.— Mr. Porritt states that the district is rich in Neuroptera 
and Trichoptera, and many interesting species should occur.
