conclusion is reached that there are no sufficient data to permit correlation of 

 the Meguina with any known series elsewhere; and the further conclusion 

 that there is no positive evidence for regarding the Meguma as Cambrian, but 

 that there is some warrant, not amounting to complete proof, for placing it in 

 the pre-Cambrian.

Fifty years ago Sir .Joseph Hooker reported that the cedars of Lebanon 

 were growing upon a terminal moraine. Since that time references to the 

 glaciation of the Lebanon mountains have been frequently made, and sweeping 

 inferences drawn concerning the influence of the Lebanon glaciers upon the 

 surrounding country, especially upon the water-levels in the Jordan valley. 

 It was for the purpose of getting more accurate information upon the subject 

 that in October. 190.3. in company with Professor Alfred Day, of the Protestant 

 College in Beirut, I set out to visit the principal grove of cedars, situated at 

 the head of the Kadisha river, east of- Tripoli. The successful outcome of the 

 expedition is largely due to Professor Day's comprehensive knowledge of the 

 geology of the range, and I hereby acknowledge my gi'eat indebtedness to him. 



The Lebanon mountains rise b,v a rapid and pretty uniform slope from the 

 eastern shore of the Mediterranean to an average elevation of 5,000 or 6,000 

 feet, and opposite Beirut and Tripoli to elevations of from 8,000 to 10.000 feet, 

 Jebel Sannin, east of Beirut, being 8,567- feet above the sea and Jebel Makhmal, 

 east of Tripoli, 10,225 feet above the sea. This range extends for a distance
