of Common and Arctic Terns were nesting, and dead examples of 
both species were found, one in each case. The heather on this, 
as its name signifies, Heather Island, was much appreciated by 
the Red-breasted Merganser as cover, a nest with eight eggs and 
another with three, the latter quite covered over with heather 
débris, being found, while old nests and unoccupied nests of this 
species were also found. Lamb Island, or Eilean Aoghainn, closely 
adjoining Fraoch Island, was another nesting site of the Red- 
breasted Merganser, Brake-ferns again supplying the cover. One 
nest had been rifled of its contents by the Carrion-Crow (Corvus 
corone, Linn.). Several of these black rascals were seen about 
the island during our visit, and they were again seen there on 
our return down the loch on the following day. We found a 
Red-breasted Merganser’s nest with ten eggs covered with down, 
and one with the extraordinary number of sixteen eggs. [Pl. 
XII.] In its vegetative aspect this was the most attractive island 
we had yet visited. Rock-Pipits abounded, and a pair of 
Common Sandpipers was pretty certainly nesting on it. Rabbits 
had established themselves here, and a few pairs of Terns 
only. | 
From Lamb Island we proceeded to the head of the loch. 
Coming down we landed at Dundarave Castle, noting here the 
Spotted Flycatcher (Muscicapa grisola, Linn.), Redstart (Ruticilla 
phenicurus(Linn.)), Wood-Wren (Phylloscopus sibilatrix(Bechst.)), 
and Tree-Pipit (Anthus trivialis (Linn.)). Here, as at Skipness 
Castle, we looked in vain for the Swift, a bird quite characteristic 
of the numerous old castles in Ayrshire, as long since pointed out 
by Gray. Resuming our journey, we reached Inveraray, and here we 
had a walk through the policy and ascended Dunaquaich. We 
were naturally very much delighted with the great woods around 
the castle, and our visit being coincident with the flowering of the 
Wood Hyacinth, we saw them with great sheets of blue in the open 
spaces, anda “hyacinthine haze”. . . “spreading round the roots” 
in the recesses of the woods. We came on an interesting pinetum on 
our way up Dunaquaich, but such collections seem to have fallen 
out of fashion. They have in a sense overstood their market, and 
this one had the neglected appearance which we have come to 
associate with them. We had not much time to spare, but we 
took the following measurements of trees which seemed to us to
