In the arrangement of the collections a series of type speci- 
mens of each group of minerals is placed first. Then follow speci- 
mens illustrating different localities, arranged in geographical 
order, passing eastward from California. Then are illustrated, 
so far as the material at hand permits, methods of mining, pro- 
cesses of reduction or manufacture, and finished products show- 
ing the uses of the metal or mineral. 
HALL 67. 
MARBLES— DECORATIVE STONES. 
This hall contains a collection of the best known foreign ^and 
domestic marbles and other decorative stones in the form of 
polished slabs. The names given on the labels are those by 
which the stones are commonly known, and in general refer to 
the color and markings of the stone rather than to the compos- 
ition or the locality where it is quarried. 
Case lA. — “Winooski Marbles,” mottled red dolomite quar- 
ried in the vicinity of Swanton, Vt. 
Other Vermont marbles. 
Case IB. — Marbles from Norway and Greece. 
Case 2. — Marbles, France. 
France is noted for the beauty and variety of its marbles. 
Examples of many of the marbles used in the ornamentation of 
our houses and public buildings may be recognized in this case. 
The names upon the specimen labels are in large part des- 
criptive — ^that is, made up of terms, each applicable to a class of 
marbles. Thus Rouge Antique is a red marble of the shade found 
in the Roman ruins.
