frosts, when scarcely a Sky-Lark has been visible for weeks, we find on the first bright sunny day 

 the stubbles are filled with them ; but these soon leave again with the least indication of returning 

 cold ; and thus they come and go till spring has fairly commenced and all our northern visitants 

 have again passed over us to their distant homes. Yarrell, referring to the migration of this 

 species, mentions having received a communication from the Rev. R. Lubbock, of his having 

 witnessed from Caister Point, near Yarmouth, ' the arrival of Sky-Larks from the sea ; ' and the 

 same has been noticed on several occasions during the month of October, by the Rev. E. W. 

 Dowell, at Blakeney. They arrive, he says, ' all day long in small flocks ; and I have observed 

 that these birds, and indeed most of the small land-birds, reach our shores in greater number 

 towards the afternoon. Larks frequently burst into song when they make the land.' On the 

 Suffolk coast they have also been seen to arrive in the same manner ; and their return in February, 

 in ' innumerable flocks,' is remarked by Messrs. Sheppard and Whitear. It would seem, more- 

 over, that these flocks are not merely confined to the daytime, from the fact of specimens being 

 frequently picked up dead, having flown against the windows of the lighthouses on the coast." 



Mr. A. Benzon sends us a note on the Sky-Lark in Denmark : — " This bird, called in Danish 

 Sanglcerke, GraslcerJce, and MarklasrJce, is everywhere common in the flat country, and places its 

 nest on the ground, forming it of straw lined with fine grass, the eggs being placed with the 

 points inwards. Its first sitting, deposited in April, never exceeds four in number, whereas in 

 June, when the weather has become milder, and the supply of food more ample, it often lays 

 five eggs. I have never seen an albino of this species ; but I know that one has been seen on 

 Jutland." 



Dr. E. Rey writes to us that he observed it in Portugal from March to May, and in Germany 

 has taken eggs of this bird from the 16th of April to the 25th of July. The average size of one 

 hundred eggs in his collection is 24T by 16-8 millims., the largest measuring 25 - 5 by 17'0, and 

 the smallest 206 by 16 millims. respectively. In number they vary from four to seven. 



Mr. Hewitson gives the following particulars: — "The eggs of the Sky-Lark, though very 

 rarely differing so much as to cause a difficulty in identifying the species, are nevertheless subject 

 to much variety, both in form and colour : some are large and oval ; others are pyriform, like 

 those of the Waders ; some are of the deep sombre brown which marks the eggs of the Titlark ; 

 others are tinted with green, and are, I think, the most characteristic of the species ; whilst a 

 few, and these are of rare occurrence, are so much less closely freckled, as to leave a light ground- 

 colour. In a nest, which I found in Derbyshire some years ago, were two of these varieties : one 

 of them resembled a good deal the eggs of the Woodlark, both in size and colour ; the other was 

 still lighter, the markings smaller, and not unlike eggs of the Pied Wagtail. These were in the 

 same nest with three others of the usual size and colour. There is yet another variety, which I 

 had almost forgotten to mention, on which the chief part of the colouring is concentrated in a 

 deep zone round the larger end; and in two or three specimens which I have seen, the same 

 deeper colouring was centred in a finger-like mark on one side only. Like the eggs of many of 

 our smaller birds, they are occasionally white." 



We have a series of the eggs of this bird, out of Dresser's collection, before us, all British- 

 taken. The ground-colour of these eggs is dull grey, occasionally with an olive tinge; the 

 underlying shell-markings are pale purplish and light brown ; and the overlying surface-blotches,
