METEORITES OF NORTH AMERICA. 311 



struck. The ground also was bare at that point, showing that the grass had been killed. The meteorite did not lie 

 at the point where it had struck, however, but about ita own width (4 inches) to the south. It had thus evidently 

 bounced southward on striking. Mr. McDonald, of Modoc, informed the writer that the stone which he found had 

 also bounded southward. Mr. Freed, of Modoc, informed the writer that the stone which he found had penetrated 

 the sod about 4 inches. This was of tabular form and was on edge. It weighed 11 pounds. 



The following list shows the individual stones which had been found at the time of the writer's visit and the 

 names of the finders. All of these masses were seen by the writer. The weights are in several cases approximately 

 only. Those that are known accurately are given in grams.

In addition the find of an individual weighing 1.5 pounds was reported by O. L. Douglass, and one weighing 2 

 pounds by F. P. Heller. Thus a total of at least 15 stones has been found, having an aggregate weight of about 

 35 pounds (16 kg.). 



The distribution of these specimens over the area in falling shows a remarkable gradation in accordance with their 

 size. The stones fell in order of their weight from west to east. This is graphically shown in a plate. The two indi- 

 viduals weighing 1 pound and 2 pounds each, found in the vicinity of the 5-pound mass, are fragments, the remaining 

 portions of which were not found although extended search was made, and the region is exceptionally favorable for 

 searching for meteorites. The smooth buffalo sod has no other stones upon it and the vegetable growth is not sufficient 

 to hide stones of appreciable size. These fragmentary individuals are shown in a plate. The complete individuals 

 would probably weigh about 5 pounds each. Some of the noncrusted surfaces of these show blackening while others 

 are perfectly fresh. The completely encrusted individuals are of irregular, angular shapes, with angles slightly 

 rounded, as is usual in meteorites. Several, however, show projecting spurs of toothed form which are unusual. No. 

 10 is especially notable for these. The three views given of this individual show its orientation. The broad surface 

 (shown in a plate) with rounded shallow pits was the rear side, the opposite the front ride. As shown by the ride 

 view, the individual is fragmentary. 



The individual found by the writer has a roughly tetrahedral form with one of the faces of the tetrahedron broken 

 up into three planes. The faces are nearly all slightly concave and show only a few broad pittings. A marked feature 

 of the surface is a whitish deposit occurring on several of the faces. This deposit is more or less streaked in appear- 

 ance, and the direction of the streaks is such that they would meet in a common point if produced. Examined under 

 a lens the deposit is seen to be a fine powder embedded in the interstices of the slaggy crust. It is soluble without 

 effervescence in hydrochloric acid, but is so small in quantity that further determination of its nature can not be made. 

 The simplest explanation of its origin would seem to be to regard it an efflorescence due to weathering, as the meteorite 

 had been exposed five months to the elements when found. The uniformity of direction of the streaks is somewhat 

 difficult to account for on this hypothesis, however. One of the uppermost faces, moreover, is entirely free from the 

 deposit. The deposit lies on what was undoubtedly the forward portion of the meteorite in falling and the radiation 

 of the streaks from a common point suggests that it was made during flight. In either case the phenomenon is new 

 to the writer's experience. The individuals shown in another plate were, as already stated, fragments when found, 

 and no adjoining parts have yet been discovered in the vicinity so far as the writer is aware. The encrusted portion 

 of one is seen to be deeply pitted, the pits varying in form and size on the different surfaces. On one surface they 

 are abundant, small, and uniformly distributed, on others fewer in number, larger, and deeper. The complete indi- 

 vidual was evidently of tabular form and about 2 inches (5 cm.) thick. One of the broad surfaces is remarkably flat 

 and shows well-marked divergent lines of flow on the crust. The other individual illustrates the internal veins which 

 occur in some specimens. These veins are evidently only armor faces produced by slipping. They are planoid in 

 character and run in various directions which often intersect. The crust of most of the individuals is dull and coal 

 black in color, though of reddish tone in some individuals. Crackling of the crust into irregular polygonal areas is a 

 common and characteristic feature, as shown in several of the plates. The crackle has a meshlike pattern with meshes 

 in the form of polygons, squares, and triangles from 0.25 to 0.5 inch on a ride. The appearance is entirely similar to 

 that presented by crackled earthenware and is doubtless produced by shrinking of the crust in cooling or expansion 

 of the interior of the meteorite subsequent to the formation of the crust. Another interesting feature seen on the crust 

 of several individuals is that of glazed spots of occasional occurrence. The spots are usually of a greenish color, oval
