which Mount Tabe and the Trois Seigneurs form the cul- 
minating points, and which extends from the Mediterranean 
to the ocean. In these places the gneiss and the granite are 
implanted in the manner of a wedge in the sedimentary for- 
mation which they turn back on one side and on the other, 
— but with this difference, that the gneiss traverses only'the 
crystalline schists, while the granite appears to cross all 
the primary rocks. 
The gneiss of the Pyrenees outcrops, therefore, in the 
same places, and in tlie same manner as the granite. It em- 
braces, like it. the schists incompletely digested, and alter- 
nates with the cipolins, talcose schists, chhjritic or amphi- 
bolitic. and with the true crystalline schists, in which it 
forms only immense lentilles. In its upper part it becomes 
granitoid or pegmatoid. And yet it is the true gneiss, lying 
at the base of all the formations. 
Dr. Jos A. Holmes, Superintendent of the department 
of Mines and Aletallurgy at the Louisiana Purchase Exposi- 
tion, was presented with a silver cup, or trophy, at a dinner 
given at the St. Louis club in St. Louis, December 2j, by his 
colleagues, in testimonv of their appreciation of his skillful 
work in the organization and management of the mining 
exhibits at the exposition.

Mr. S. Harbert Hamilton announces that he has sold 
to the Carnegie museum Pittsburgh. Penna., Mr. W. W. 
JefYeris' famous collection of minerals, with the Under- 
standing that it is to be known in perpetuity as "The W. 
W. Jefferis Alineral Collection of the Carnegie ^luseum." 
Mr. Jefferis began the collection of minerals more than seventy 
years ago. Living at West Chester, Chester county, Penna., he 
had unusual opportunities of collecting choice specimens from the 
ancient gneisses, serpentines and limestones, as well as from the 
trap rocks, of eastern Pennsylvania, New .Jersey and New York, for 
at that time mining was carried on more extensively in this region 
than at present. Mr. .Jefferis did not confine himself to this local- 
ity, however, in his search for minerals, but also visited northern 
New York, Canada and Europe; and in making exchanges with 
other collectors all over the world he sent out hundreds of boxes 
of minerals. He spent as lavishly of his means as he did of his 
time in gathering together with the eye of a connoisseur, this 
marvelous collection, so that it now goes to Pittsburgh as one of 
the finest private collections of minerals in America. 
Mr. Jefferis, although primarily a collector, was also a dis-
