are usually placed in the birch trees at heights of from four to 
eight feet, and the number of eggs never more than four. They 
are composed mostly of fine straws and bents, mixed with moss 
and lichen, a layer of still finer bents being put in as lining, over 
which is a final layer of feathers. 
House Sparrow. Passer domesticus.—A few were seen about 
the station at Aarlivold as we passed through on May 17th, and 
several old nests were stuck among the timbers, but this was the 
only place we noticed it north of the Dovrefjeld. 
Hooded Crow. Corvus cornix.—These were very numerous at 
Nervig, feeding on the enclosed land, as a lot of Rooks might do, 
and one nest was taken on May 16th by Wrigley, there being four 
eggs, a little sat upon, in a small tree on an island at the mouth of 
the River Orkla. We found them as far as Drivstuen, but never 
saw them on the Dovrefjeld. 
Magpie. Pica caudala.—Common everywhere; numbers of 
nests in the trees along the streets of Trondhjem, and close to 
boxes placed for the reception of Starlings. At Nervig was 
one within three yards of the ground, and at Jerkin we noticed 
one built among a heap of sticks reared against the barn-wall. 
At the former place, on May 14th, we took a nest of seven eggs, 
and there were many more nearly as far advanced. A nest near 
Fokstuen station-house was about eight feet from the ground in a 
small birch, and whilst in process of building was quite inaccess- 
ible from the melting snow forming a swampy lake round it, but 
when all this went it was left high and dry, and we visited it every 
morning to remove the newly-laid egg. She deposited seven, the 
last on June 10th, but would do no more for the furtherance of 
oological science. 
Jay. Garrulus glandarius.—Two pairs seen at Grut, May 
18th, the only ones observed. 
Siberian Jay. Perisoreus infaustus—When driving through 
the thick pine-woods between Austberg and Stuen, May 20th, a 
Siberian Jay crossed the road in front of us, but the guns happening 
to be packed up she went on her way rejoicing. 
Great Black Woodpecker. Dryocopus marlius.—On May 21st 
we had not left the station-house at Stuen above ten minutes when 
in a tall pine we descried a big hole, evidently the work of a 
Woodpecker. ‘Iwo of us went back for a ladder, and whilst car- 
rying this to the place the gun went on, and on our arrival Wrigley
