not find in the galena limestone above it. (2.) This zinc strata 
underlies the entire lead district. (3.) As before stated, it has 
been reached in but a very few places in the mines. The con¬ 
clusion to be drawn from these facts is, that we have a large 
amount of undeveloped mineral deposits above the sand¬ 
stone which offer peculiar inducements to mining, or will do 
so, as soon as a steady and reliable market for this ore is estab¬ 
lished by manufacturing it in our own state, and in close prox¬ 
imity to the mines. 
The principal object of this survey has been to bring to light 
these facts that relate to the origin of our mineral veins; their 
relation to the lower strata, and to mineral veins in general. In 
presenting them in this report, I have made no effort at style 
or literary display, but to present them in as plain, simple lan¬ 
guage as their nature will admit. It must not be regarded as 
a scientific report, but a presentation of facts for practical pur¬ 
poses, and for the use of practical men. 
Before closing I wish to make the following proposition: I 
have found it impossible under our present system of mining 
to collect material for a reliable statistical report. And, inas¬ 
much, as a reliable record of the amount of ores raised in the 
different mines is important to the future success of these in¬ 
terests, I make the following suggestion, or rather proposition, 
namely, that if parties owning mines will furnish me annually 
the amount of ore raised in their individual mines, or any other 
item of information of importance, I will make a record of it, 
and from the different items, prepare and publish a report an¬ 
nually, without any expense to them or to the state. Another 
proposition. 
Inasmuch as we have commenced a museum of practical 
geology, under the auspices of the Wisconsin Academy of 
Sciences, Arts and Letters, and have already quite a collection 
of minerals, fossils and other specimens, representing the prac¬ 
tical and scientific interests of the lead district, and as such a 
museum will be an honor to our state, and is almost essential to 
the success of our mining interests, if parties in the mining 
region or in any other part of the state will collect and forward
