be made to Messina, where the steamer will be 

 taken to Naples again. This excursion will 

 not cost more than 358 lire. The third excur- 

 sion is a variant of the preceding, but gives 

 more time to Naples and its vicinity. It al- 

 lows three days for Naples, and joins up with 

 the other excursion at Catania. The cost will 

 be about 366 lire. All excursionists are in- 

 vited to visit the exhibition at Turin on No- 

 vember 1, and on the evening of that day the 

 excursion will be regarded as closed.

DISCUSSION AND COBSESPONDENCE 



the grand canyon of the COLORADO 



On page 89 of Science, No. 864 (July 21, 

 1911), I observe a special article by H. H. 

 Eobinson entitled " The Single Cycle Develop- 

 ment of the Grand Canyon of the Colorado." 



During the summer and autumn of 1908 I 

 spent several months in the Grand Canyon in 

 the region about Shinumo Creek, making a 

 study of the geology of the Shinumo quad- 

 rangle. The results of this study were pre- 

 sented at Yale University in the form of a 

 Doctor's thesis, a part of which, dealing with 

 the rocks of the Vishnu and Grand Canyon 

 series, has been published in the American 

 Journal of Science (May and June, 1910) 

 under the title " Contributions to the Geology 

 of the Grand Canyon." I have since returned 

 twice to the region to extend the same study 

 in the interest of the United States Geolog- 

 ical Survey; the entire report on the geology 

 of the Shinumo quadrangle is to be published 

 at a future date as a Bulletin of the Geolog- 

 ical Survey. 



My observations in that region (recorded 

 in the thesis, but not yet published) are en- 

 tirely in accord with the conclusions of Davis 

 and Eobinson in regard to the dependence of 

 the benches in the canyon upon the character 

 of the strata.
