WILLAMETTE METEORITE. I43 



It would be a serious omission not to call attention to the possi- 

 bility, and even strong probability, that the great mass has contained 

 great nodules or even long cylindrical inclusions of some mineral 

 softer and more easily yielding to attrition than is the iron of which 

 it seems to be wholly composed. We know that inclusions of troilite 

 are frequent in siderites, in some of which, as for instance, Toluca, 

 Youndegin, Canon Diablo and Bella Roca, they occur in masses of 

 some volume. We suspect that the Willamette may contain such 

 troilite inclusions, and that they may have both determined the posi- 

 tion and have greatly enlarged these excavations. This is particu- 

 larly true of the long furrows, two of which are so prominent in plate 

 14. In these, the upper part of the wall hangs over as a rim, leaving 

 the tube or gutter, as seen from the side, larger within than in its 

 outside exposure. These furrows, as well as one of the holes, gouge 

 deep recesses out of the otherwise continuous border of the mass. 

 As is noticeable in plate 13, the lower part of the cone rolls smoothly 

 around to join its base. 



At this point in our paper we leave the cone or brustseite of our 

 meteorite ; repeating here that the three cuts taken before our arrival 

 show the mass upright ; nearly the reverse of the way we saw it. 

 Plate 15, figures i and 2, taken from either end, show well the relation 

 of the great meteorite cone to its base. With them, notably figure 2, 

 •is first revealed the second series of wonders of our most wonderful 

 and absolutely unique meteorite. 



On the base of the mass we shall see added phenamena. Plate 16 

 shows the full surface of the base of the great meteorite — its length, ten 

 feet ; its breadth, seven feet. It will be seen that its original surface was 

 slightly crowning : also that this surface was covered with well-devel- 

 oped normal pittings of great similarity of character in all its parts. 

 The remaining areas of this surface are in every case thus covered. 

 Furthermore we observe the striking manner in which the base of our 

 mass was drilled and bored by the clean, round holes which we have 

 already noticed as existing in moderate numbers on the brustseite. 

 Counting only those which are of limited diameter, there are over 

 thirty of them, varying from a half inch to two and one-half inches 

 across, and from three or four inches to an unmeasurable depth. 

 Indeed, quite a few of them which are near the periphery, pass 

 completely through the mass, as we noted when describing the other 

 side. One of these perforating vertical bores or drill-holes is 

 seen at the base of the figures ; the other two are visible toward the 

 extreme left. The position of these upon the base, the rear side of
