THE NAUTILUS. 113 



cabin at that point was a tight-wad and had locked the door 

 when he left, and thus we slept out a couple of nights. 



The Mogollon Mountains at this point run up to 10,500 feet 

 and are termed rough. The roughness consists of granite, 

 quartzite, and various forms of igneous rock, so far as snail 

 hunters have explored. Rocks resembling limestone, and so 

 termed, were found to be a volcanic product. 



Above 7,000 feet the timber is heavy and plentiful. Yellow 

 and White Pine, White and Cork Bark Fir, Pseudo Hemlock, 

 Oak and Quaking Asp predominate. Cotton woods, Sycamore and 

 Walnut dominate the lower valleys, and the Junipers rule in 

 the foot-hills. 



It is a large range for the Southwest, at least 100 miles long 

 and thirty to forty wide ; drained southward by tributaries of 

 the Gila, the San Francisco and the Membres rivers. 



The indications furnished by these few canyons in a large 

 number opening to the South point to a fruitful field. A well 

 equipped party would require at least one year in which to 

 make a hasty survey. The rainy season starts about the first 

 of July and continues until the middle of August. The sum- 

 mer of 1914 was something unusual however and we had a 

 shower every day except three. Rain however is pleasing to 

 snails. After a good shower they travel over the stones for half 

 a day. The climate above 5000 feet is cool enough for comfort 

 at that season of the year in truth the temperature is perfect. 



The mountains of the Southwest are inexhaustible to the con- 

 chologists of this generation. Should any desire to assist in this 

 work, in the Mogollon or other ranges of which we have know- 

 ledge, the}' will find us prompt with both information and advice. 

 There is a larger country than we can hope to explore, all 

 within the states of New Mexico and Arizona. 



In another article we hope to give a detailed account of the 

 snails collected, in cooperation with Dr. Pilsbry, a companion 

 on other Arizona and New Mexico expeditions.
