the lakes in the volcanic mountain region. 

 He found Lake Atitlan, Guatemala, to be the 

 deepest, being 1,000 feet deep, and the largest, 

 being 24 miles long and 12 wide. It was also 

 the coldest, being, in spite of the tropical 

 climate, but 67 degrees. Its elevation is 5,000 

 feet above the sea level. Pish and vegetable 

 life he found to be scarce in all these lakes of 

 the volcanic region. In San Salvador he ex- 

 plored Hopango, Y27 feet deep, and Coate- 

 peque, 350 feet deep; and in Guatemala Lake 

 Amatitlan, 110 feet deep. Although Hopango 

 had two islands raised in it by volcanic action 

 thirty years ago, Mr. Juday now finds no 

 trace of such action there.
