ii'l Tin American Geologist. January, 1^94 
composed of four mines, the Triana, San .lose. San Fructuoso, 
and Mayor. 
There are eighteen groups of manganese mines and three 
groups of mines of chromic iron; also three groups of lend 
mines, one of the latter containing zinc, silver and gold, and 
the other two lead and silver. 
All in all, the mining- industries of Cuba, both in metals, 
which have been briefly noticed, and in asbestos, asphalt and 
guano, are well represented and industriously and systemat- 
ically catalogued, in the otHeial guide in the Spanish language. 
It is to be regretted that the mother country is so ill repre- 
sented in the building.

In summing up the notes made on this display of the ores 
of gold and silver and of copper, iron, tin. antimony, lead. 
etc., etc., it is incontestable that an assemblage of ores grati- 
fying to the eye has been made. Many of the individual ex- 
hibits are complete and their framing is made in good taste 
and with conscientious fidelity, and } T et as a whole it is disap- 
pointing, not so much on account of inadequacies and total 
deficiencies (though these are very frequently apparent) 
as because it is rare to observe any effort to use the collec- 
tions for the instruction of the public. The aim has been to 
dazzle and please the eye, but those who went through the 
separate pavilions prepared to study and profit by their con- 
tents have not been sufficiently recompensed for their time. 
No uniform system was adopted for the pavilions as a 
whole nor for each by itself. It was too apparent that the ar- 
rangement was governed b} T the sizes rather than by the char- 
acters of the objects, and by the desire to impress the visitor 
with the magnitude rather than to teach him. Much negli- 
gence was shown in the detail of labels, and the fact was not 
sufficiently considered that what might be a sufficient de- 
scription of an object in a case containing a small collection, 
was very insufficient for a world's fair. The labels them- 
selves were too often missing, incompletely made out or use- 
less on account of being covered by the specimens. Many of 
the most important localities have not been represented at all.
