which we know as St. Mary's River is the true Belly River. 

 This seems natural and proper, for at the point where they 

 meet, the St. Mary's is a larger stream than Belly River. 



As stated by Mr. Doty these lakes are two in number, the 

 lower about seven miles long by a mile wide, the upper per- 

 haps eleven miles long and nowhere more than a mile in 

 width. The lower lake lies north and south, and the upper, 

 Mr. Doty's Bow Lake, is bent about half-way up its length, 

 its upper or south-western half lying nearly east and 

 west, and its lower or northern half nearly north and south. 

 Beyond the head of this upper lake is the narrow river-val- 

 ley running back in two principal branches for a dozen miles 

 and heading on the Continental Divide. The southernmost 

 of the two branches is much the larger of the two, and is fed 

 by extensive glaciers, which I have visited. 



The lower end of the lower lake is not more than seven or 

 eight miles from the Chief Mountain, the most striking 

 landmark in this region. The waters flowing into the St. 

 Mary's River are divided from those which flow into Cut 

 Bank and Milk Rivers, tributaries of the Missouri, by a high 

 ridge running out from the Rocky Mountains, and known 

 as Milk River Ridge. 



BIRDS BREEDING AT HANOVER, NEW HAMP- 

 SHIRE. 



BY CLARENCE M. WEED. 



The village of Hanover, N.H., is in the region dividing 

 the Canadian and Alleghanian faunas, and possesses many 

 animal forms from both. To assist in determining more 

 definitely the precise limits of these faunas, the Ornithologi- 

 cal Club of the New Hampshire College undertook last 

 spring to record the birds breeding within five miles of Han- 

 over. The following list includes the species observed this 

 season by the members of the club. Especial mention should 

 be made of the assistance rendered by Messrs. P. L. Barker, 

 E. A. Campbell, and C. E. Hewitt. 



Green Heron, Ardea virescens. One nest observed. 



American Woodcock, Philohela minor. Three nests ob- 

 served. 



Ruffled Grouse, Bonasa umbellus. Three nests observed. 



Cooper's Hawk, Accipiter cooperi One nest observed. 



Acadian Owl, Nyctala acadica. One nest observed. 



Black-billed Cuckoo, Coccyzus erythrophalmus. One nest 

 observed. 



Belted Kingfisher, Geryle alcyon. Two nests observed. 



Downy Woodpecker, Picus pubescens. One nest ob- 

 served. 



Golden-winged Woodpecker, Colaptes auratus. Two nests 

 observed.

 outsiders within three miles of the village.

 link's nest.

 breeding here, but it may serve as a basis for future obser- 

 vations.

HOT WEATHER IN MARS. 



BY PROFESSOR EDWIN J. HOUSTON. 



The recent severe, protracted, hot weather, that existed in 

 the central and eastern portions of the United States during 

 the latter part of July, formed, in all probability, but part 

 of various general phenomena produced by profound solar 

 disturbances. 



So many of the earth's natural phenomena find their 

 origin in the solar radiation, that it is impossible to vary 

 either the amount or the distribution of the solar energy 

 without markedly modifying terrestrial phenomena. Such 

 influences, however, are not limited to terrestrial phe- 

 nomena; they must extend beyond the earth and be shared 

 by all the members of the solar system.
