BOTANICAL SECTION. 
(J . Fraser Robinson) Perhaps the remarkably long, dry and 
fine season, which still continues this second week of October, is re- 
sponsible for a marked revival or big increase in the activities of the 
field botanists during the year. On no former occasion could one report 
the receipt by one at least of your secretaries of so much botanical corre- 
spondence, with plant specimens for confirmation, identification and so- 
forth, as has been the case of late. From places as far separate as Goath- 
land and Skipwith, Wensleydale and Brantingham Dale, we have had 
many plants and numerous lists of plants ; and it is pleasing to note 
that these were from members or associates of the Y.N.U. who, perhaps, 
have long been interested, although most unobtrusively, in plant study 
and classification. True, the confirmation of old records and the 
discovery of new plant-stations have constituted the bulk of the work 
done, but it has not been entirely without ‘ new to Yorkshire,' or even 
‘ new to Britain.’ The recently found Tillaea aquatica in W. Riding 
and the White Helleborine ( Cephal anther a Damasonium Druce) in an 
E. Riding Beechwood on the chalk, are instances in point. 
This season has been mentioned ; but it has been really a kind of 
double season. The long drought in the early part thereof, brought 
forward the flowering period which was consequently soon over. Since 
then the drought having been broken somewhat, there has been a remark- 
able vegetative resuscitation with a corresponding flowering period. 
During the early autumn, many flowers have been almost as much in 
evidence as they were last spring. Thus White Dead Nettle, the Creeping 
and Acrid Buttercups, and even Laburnum and Lilac have made a novel 
sight ; whilst in gardens in the E. Riding, a week or two ago, the new 
Raspberry canes were in flower. 
The number of competent observers of the crops of fruit, has been: 
larger than usual ; and many reports show that Apple, Pear, Oak, 
Bramble and Rose^have good fruit crops generally. In certain districts, 
the same may be said of Sycamore, Ash, Elm, White Beam and Mountain. 
Ash, although in others the crop of fruit on these is only very fair or fair. 
Of the Pruni (Sloe, Bullace, Damson, Plum, etc.), the fruiting is very 
poor or absolutely nil, which will be accounted for by their very cold 
blossoming time. The same may be said of the Beech tree which has no 
fruit this season . Horse Chestnuts are scarce ; likewise Haws ; and 
shrubs like Dog-wood, Guelder-rose, Yew, Privet, etc., are apparently 
in the same category. One observer mentions the fact that the Manna 
Ash ( Fvaxinus ornus ) has flowered well within the city boundary of 
Sheffield during the summer, but he did not discover any fruit. 
One cannot write a botanical report without referring to the great 
loss that this section and the Y.N.U. generally have sustained by the 
deaths during the year of such able botanists as the late J. G. Baker, 
L. C. Miall and F. Arnold Lees. Those of us who are still left in the 
field could say much more on this mournful point. We content our- 
selves with brief mention in very grateful memory.
