over the intruded mass labeled 'lava,' seem- 

 ingly with the intention of indicating that the 

 intrusion did not reach the surface. We know, 

 however, from the writings of Major Button 

 that the volcanic necks in the Mt. Taylor re- 

 gion, the one selected, are the plugs hardened 

 in the throats of normal craters. 



An exception might be taken to the use of 

 the word crater in reference to the great 

 depression in the summit of Mount Mazama, 

 but such a distinction I believe, was not made 

 by Dutton and Diller, to whom we owe nearly 

 all our information concerning the region in 

 question. 



In the interest of the large number of 

 teachers and students who will consult the 

 topographic folios of the U. S. Geological 

 Survey, I venture to suggest that the descrip- 

 tions accompanying the maps should be 

 written by persons who are familiar with the 

 regions represented and have a critical knowl- 

 edge of their geology. These texts, although 

 of necessity brief, should not be stultified 

 compilations, but Nature herself speaking 

 through a master interpreter.

SCIENTIFIC JOUR!sALS AND ARTICLES. 



The .Tournal of School Geography, edited by 

 Richard E. Dodge, of Teachers College, Co- 

 lumbia University, enters upon its fifth vol- 

 ume in January. The editorial staff will be 

 strengthened by the addition of Mr. Mark S. 



W. Jefferson, of the High School, Brockton, 

 Mass., who will devote his attention to Second- 

 ary School Geography, and of Miss Ellen C. 

 Semple, of Louisville, Kentucky, who will, as 

 before, contribute articles and notes in reference 

 to Anthropo-geography. 



The Plant World for November opens with an 

 illustrated article on ' An Ornamental Species 

 of Bideus^ by G. N. Collins. It is a little ir- 

 regular to learn that the now popular Cosmos 

 flower was brought from Mexico twenty years 

 ago and cast aside as a worthless weed. F. M. 

 Burglehaus tells of ' Drying Botanical Dryers 

 in Wet Weather ' and Charles Newton Gould 

 describes the ' Jack Oaks in Oklahoma' which 

 are practically useless for anything save fire- 

 wood. Charles A. White discusses ' The Va- 

 rietal Fruit Characters of Plants' and 'Eng- 

 lish and American Weeds [are] Compared' by 

 Byron D. Halsted with the result that in 100 

 species from each region less than one quarter 

 of them are common to both lists. In the Sup- 

 plement devoted to ' The Families of Flowering 

 Plants,' Charles Louis Pollard treats of the 

 orders Fogales, Urticales and Proteales. 



No. 38, vol. 8, of the Bulletin of the New York 

 State Museum is devoted to a ' Key to the Land 

 Mammals of Northeastern North America ' by 

 Gerrit S. Miller, Jr., intended to furnish a 

 ready means of identification with the least pos- 

 sible technical requirements. Keys are fur- 

 nished to the various orders, families, genera, 

 species and even subspecies of the mammals 

 inhabiting the region noted, while references 

 are given to the first publication of each name, 

 the first use of the binomial or trinomial combi- 

 nation and to some recent work in which the 

 animal is described in detail. Recently extir- 

 pated animals, such as the bison and walrus, 

 are included and there is a short introduction 

 defining the areas of the life zones of the region 

 under consideration, and before the 'Key' 

 proper is a check list of the 105 species treated. 

 The work is not only useful for the amateur, 

 but of great value to the working zoologist, as 

 Mr. Miller is among our leading authorities on 

 mammals and has devoted particular attention 

 to those of New York State and the adjoining 

 territory.
