of my work for a number of years past. The same method was 

 applied during a geographical excursion across northern Italy 

 and into southeastern France from June 1st to July 18th, when I 

 had the advantage of discussing its application to various problems 

 with some fifteen European and American geographers who 

 accompanied me for longer or shorter periods. We visited in 

 succession the dissected coastal plain in the neighborhood of 

 Ancona, the re-deepened valley of the Lamone near Faenza, the 

 basins of Florence and Val d'Arno, the simple shore-line near Pisa, 

 the complicated shore-line between Spezia and Genoa, the elbow 

 of capture of the Tanaro at Bra, the over-deepened Alpine valleys 

 in whose terminal depressions lie the superb lakes of Como and 

 Maggiore, the great terminal moraines of Ivrea, the valley of 

 Aosta, various parts of the valley system of the Isere, the dissected 

 slope of the Cevennes, and the volcanic district of Le Puy. 



Following this excursion I attended the International Geo- 

 graphical Congress at Geneva, and served there as President of the 

 section on Educational Geography.
