REPORT OF NATIONAL MUSEUM, 1895. 



MASON, Otis Tufton — Contiuued. 



The object of this paper is to study the man- 

 ufacture, the ethnographic, and the geographic 

 distribution of all the types of bows, arrows, 

 and quivers among the North American tribes. 

 The plan lias been to treat these objects as 

 specimens of natural history, and to consider 

 their structure, function, and distribution on 

 the line of environment and of evolution or 

 elaboration, in a series of explanatory pages. 

 Each separate piece is described as minutely 

 as possible, so as to render the specimens in 

 question types for future investigation. 



Overlaying with copper by the 



American aborigines. 



Proc. TJ. S. Nat. Mus., xvn, Xo 1015, Jan. 

 26, 189.5, pp. 475-477, figs. 1-4. 

 This paper is based on two examples from 

 the Tlinget Indian.s, Alaska, in which two 

 wooden birds have their wings overlaid with 

 cold-hammered sheets of copper and then en- 

 graved with totems. 



Historic and ethnologic science. 



i;poc;i, 1, 1895, pp. 3-11. 

 The object of this paper is to show that the 

 two lines of study, the historic and the ethno 

 logic, are indispensable one to the other for in- 

 vestigating the progress of human culture. 



Similar inventions in areas wide 



apart. 



Science (New series), 1, 1895, pp. 235-236. 

 This paper calls attention to the wide dis- 

 persion of a weaving frame or harness consist- 

 ing of a series of slats, each one pierced in the 

 middle. The warp threads pass alternately 

 between the slats and through the holes, and 

 this enables the weaver to shift the warp The 

 question is raised whether the Pueblo Indians 

 invented this apparatus or received it from the 

 Europeans. 



The distribution of sledges. 



This article calls attention to the factthat no 

 sledge, snowshoe, or goggle has ever been dis- 

 covered in South America.

MERRILL, George P. On the formation 

 of stalactites aiid gypsum incrustations 

 in caves. 



Proc. 77. S. Nat. Mus., xvu, No. 985, July 

 23, 18S4, pp. 77-81, pis. Il-V. 

 Describes the peculiar vermicular and kniirly 

 .stalactites of Wyandotte and Luray caves, and 

 ascribes their formation to the action of capil- 

 larity. Also describes the peculiar curved and 

 rosettiform gj'psums from Mammoth and Wy- 

 andotte caves, ascribing their form to condi- 

 tions of strain under which th(> spicules were 

 pushed outward by growth from the bottom. 



The formation of sandstone concre- 

 tions. 



Proc. 77. S. Nat. Mus., xvn. No. 987, July 

 23, 1894, pp. 87-88, pi. VI. 

 Describes the formation of concretions 

 through the oxidizing influence of water and 

 air on concretionary ma.sses of marcasite.

Notes on some eruptive rocks from 



Gallatin, Jeiferson, and Madison coun- 

 ties, Montana. 



Proc. 77. S. Nat. Mus., xvn. No. 1081, May 

 11, 1895, pp. 637-673. 

 Describes the petrographio character of a 

 series of rocks collected by the author and Dr. 

 A. C. Peale, of the IT. S. Geological Survey, 

 during several seasons' field work iai the region 

 mentioned. 



Disintegration of the granitic rocks 



of the District of Colunxbia. 



Bull. Geol. Soc. Am., vj, 1895, pp. 331-332, 

 with plate. 

 The author describes in detail the phases of 

 the granitic disintegration, and gives analyses 

 of fresh and disintegrated material. The dis- 

 integration 18 shown to have taken place since 

 Cretaceous times, and to be accompanied by a 

 comparatively small amount of decomposition. 

 The theory is advanced that the disintegration 

 is due mainly to hydration.
