down on to a ledge, calling out a hoarse croak, and flying out 
again to its mate. After taking careful bearings of this ledge to 
enable us to know where to stop, we at once begin to climb 
up. The point is at length reached, and after some trouble one 
is able to look along the narrow ledge, where, to our joy, the new 
nest is found. However, it is not possible for us to look into 
the inside of it from this point, so that for this purpose we have 
to climb higher still. Then crawling along on all fours and 
running some risk, the edge of the precipice is thus gained, and a 
view of the inside of the nest obtained. It contains three young, 
as far as we can discern, which accounts for the behaviour 
of the two old Ravens when we approached the crag, and now 
they are wheeling close above our heads, croaking the whole 
time. While we are at this point we are attracted by the call of 
the Peregrine, and on looking up we see four of them keeping 
apart in pairs. Down in the valley, conspicuous by their white 
rumps, are a number of Wheatears, hopping swiftly from mound 
to mound as we approach them. 
April 6th.—In the afternoon we walk up along the left bank 
of the River Cegin. Having been told of a Dipper’s nest at a 
certain place where one was known to us last season, we, on 
coming to the spot, begin to search, and soon come across it, 
and find that it contains young. On proceeding along we per- 
ceive a Grey Wagtail as it flits by down stream with its undu- 
lating flight, and uttering a sharp “‘zisy.”” Further on up the 
river we come across another Dipper’s nest, built against a steep 
mossy rock on the opposite bank. 
Easter Monday.—Thinking of visiting another Raven’s haunt 
that we knew of, and which needs a whole day to reach and 
return, we leave the town by the 7.50 a.m. train. Our journey 
by railway is only short, but before we arrive at the little 
station where we are to alight we see, when looking through 
the carriage-window, a brace of Partridges squatting low as 
the train rumbles past them. On alighting we deliver up 
our tickets to the stationmaster, who was the sole person on 
the little platform, and who bids us a pleasant walk. Passing 
a large rookery, where all the Rooks seem very busy, we 
enter into a narrow valley which is exceedingly well-wooded, 
and here we obtain a glimpse of a Sparrow-Hawk. A tramp
