often admits others to share with him, and they join with him in forming a

company, and they each lay out a part of the expense and share with him

the profit or loss of the mine. </

undivided, although for the purpose of dividing the expense and profit it

<
s

must be understood with regard to a tunnel, may be divided into two halves,
<

that is into two similar portions, by which method two owners spend
<

an equal amount on it and draw an equal profit from it, for each possesses
<
lb

one half. </
s

<
s
>Sometimes it is divided into four shares, by which compact

lb

four persons can be owners, so that each possesses one-fourth, or also two
<
lb

persons, so that one possesses three-fourths, and the other only one-fourth
<
gap

<
lb
/>
or three owners, so that the first has two-fourths, and the second and third
<
lb

one-fourth each. </
s

<
s
>Sometimes it is divided into eight shares, by which plan
<
lb

there may be eight owners, so that each is possessor of one-eighth; some
<
lb

times there are two owners, so that one has five-sixths

together with one
<
lb

twenty-fourth, and the other one-eighth; or there may be three owners, in
<
lb
/>
which one has three-quarters and the second and third each one-eighth;
<
lb
/>
or it may be divided so that one owner has seven-twelfths, together with
<
lb
/>
one twenty-fourth, a second owner has one-quarter, and a third owner has
<
lb
/>
one-eighth; or so that the first has one-half, the second one-third and one
<
lb

twenty-fourth, and the third one-eighth; or so that the first has one-half,
<
lb

as before, and the second and third each one-quarter; or so that the first
<
lb

and second each have one-third and one twenty-fourth, and the third one
<
lb

quarter; and in the same way the divisions may be adjusted in all the other
<
lb

proportions. </
s

<
s
>The different ways of dividing the shares originate from the
<
lb

different proportions of ownership. </
s

<
s
>Sometimes a mine is divided into
<
lb
/>
sixteen parts, each of which is a twenty-fourth and a forty-eighth; or it may
<
lb
/>
be divided into thirty-two parts, each of which is a forty-eighth and half a
<
lb
/>
seventy-second and a two hundred and eighty-eighth; or into sixty-four
<
lb
/>
parts of which each share is one seventy-second and one five hundred and
<
lb
/>
seventy-sixth; or finally, into one hundred and twenty-eight parts, any one
<
lb
/>
of which is half a seventy-second and half of one five hundred and seventy
<
lb

sixth.</

four, or occasionally more shares, which depends on the excellence of the
