Editorial Comment. 59 
The works, or diggens made or realized in this Mine are conipossed, 
of tow wells, one of 125 feet deep and the other of 75 feet, connected by 
themself with a principal gallery only 25 feet deep onder the level of the 
ground. 
There are, distinctly to the sight, as well in the gallery as in the 
wells, different vein of ore and lines producing gold; and of one this 
lines, which runs all throug the gallery and is 12 inches wide all along is 
the piece of gold wihich is at sight. 
From this same vein of ore, or line it has been drawed out four Tons 
of Mineral which after been melted and grinded (empirically way) and 
without any scientiflcal direction; — and only to trie the Engine and 
Grinder have produced four small bars of pure gold one weighing six- 
teen ounces which was sold for the price of $300 and the other is the 
piece joined to the Mineral and at sight to the public which optained 
the first primiun at the Regional Exposition of Santa Clara.

Iron. 
Jose Ruiz, of Leon, was the first to "denounce" an iron mine 
in Cuba (so saj^s the Spanish guide book), which he did 
three or four minutes past noon on the 26th of January, 1881. 
Without the initiative of the gentleman (it adds) these rocks 
would have been forever undiscovered! ! ! 
The first group, distant from Santiago de Cuba about six 
kilometers, is three kilometers in extent and is called Dorotea. 
It is composed of five mines entitled San Lino. San Ignacio, 
Dorotea, S'tra S'ra, del Reereo y Criolla, with a total area of 
300 hektares. The analysis of these ores is as follows: 
Moisture 0.95 
Metallic iron .. 63.20 
Metallic manganese 0.90 
Silica 0.42 
The second group is that of the Sevilla and Ocana, eight
