mainly of dry leaves, lined with fine roots, moss fibres, pine nee- 

 dles, and horse-hair, and placed in canes over water at heights 

 varying from four to eight feet. Of the seven eggs taken, four 

 were immaculate, two perhaps slightly spotted, and one unmis- 

 takably spotted and blotched with lilac. 



The inferences suggested by these facts are : (i) That Swain- 

 son's Warbler nests usually, if not invariably, in canes over water ; 

 (2) that it lays from one to three eggs ; (3) that its eggs may be 

 either plain, slightly speckled, or rather thickly and distinctly 

 marked. 



Another season's work on the part of Mr. Wayne will doubtless 

 throw more light on all these points. Meanwhile ornithologists 

 may well rest satisfied with the knowledge thus far obtained.

The present article, based on observations made and material 

 collected in the pine region and neighborhood of Las Sierras de 

 Santa Catalina, Pima County, Arizona, is in reality a continua- 

 tion of an article which appeared in ' The Auk ' for April, iSS^ 

 (pp. 172-174). The locality visited is the one there described. 

 The duration of my stay was from April 19 to 24, inclusive. 



The winter snow had almost melted from the ground and was 

 only to be seen in patches in the deeper part of the woods and 

 on the sides of hills and ravines, where the sun shone but little. 

 It was still cold, and ice formed at night on water standing in 

 pails, and on the edges of the mountain brooks where the current 

 was not too swift. Except on the morning of the 21st of April, 

 and throughout the entire day on the 24th of the month, the wind 

 blew incessantly and most of the time with great force. Oh the 

 20th, about daylight, a cold storm of rain and hail set in, and later 

 this changed into snow, which soon covered the ground to the 

 depth of nearly an inch. The storm, however, broke about noon,
