the Water Vole, very common at the beck-side ; the common Field Vole, 

 the Hare, and last, but by no means least plentiful, the Rabbit, which crossed 

 our path every score yards or so. The district is not such as to allow the 

 ornithologist to present a very long list of birds, Ijeing flat, and possessing 

 little physical diversity. Owing to absence of moorland, such birds as the 

 Ring Ouzel, Golden Plover, and Red Grouse are wanting, as are also many 

 of the smaller birds, probably owing to the fact that the woods are remark- 

 ably devoid of underwood. The district is drained by a sti-eam knowa as 

 Cock Beck, which empties itself into the Wharfe below Tadcaster. This 

 stream is renderetl famous by the very sanguinary engagement which took 

 place on its banks near Towtou, aboxit two miles from Aberford, on Palm 

 Sunday, 1461. It is of a sluggish nature, and not attractive for such birds 

 as the Heron, Kingiisher, Sandpiper, and Dipper, but admirably suited for 

 the Water Hen, several of which were seen. The following is a complete 

 list of the birds recorded : — Missel Thrush, Song Thrush, Blackbird, Whin- 

 chat, Redstart, Redbreast, Whitethroat, Lesser Whitethroat, Blackcap, 

 Garden Warbler, Chirt" C!hatf, Willow Warbler, Sedge Warbler, Hedge
