But the Zimball ruins show that this

Machines for opening and cleaning
cotton have recently been improved by
an automatic feeding apparatus, applied
to the feed apron, and by means of
which one man can tend two machines
when being fed with raw or bail cotton
easier than he could heretofore tend
one. A large amount of seeds and leaf
is extracted by this device.
"A German botanist, Mr.. Regel, has
recently given to the public the result
Of his researches as to the causes of the
perfumes of plants, and the factors
which diminish or increase them Light

ant role. Darkness prevented the de-
velopment of perfume in flowers Of
which the buds were only slightly adj
vanced when submitted to its influence
and even the plants whose flowers ex-
hailed perfume only at night lost their
odor if compelled to live in continued
darkness. Paris Revue Scienti6que.
1t has been claimed that the seeds

Some idea of the faith and patience
which the California miner displays
may be gained from the case of the Cen
tennial gravel mine in Nevada county,
For eighteen years work has been car
ried on in tunnel which is now one
third of mile into the mountain to a
large vein of blue gravel that always
carries d large amount of gold About

without cent in return, yet the stock
holders are confident that when divi-

1t is reported that recent borings for
artesian wells in South Dakota have
disclosed an extraordinary variety of
clays, gravels and quicksands hundreds
Of feet deep, beneath which is a hard
rock resembling granite. The cretaceous
formation abounds with remains OF
plants, animals and fossils, among
which are those of fig tree and five
new species of fish, three of them here
tofore unknown to science. This of
itself is interesting, but most extraor-
binary is the conclusion drawn by
scientific men that the area lying be-
tween the quartz line and the Lauren
an-duronian line was once the bed OF

Paper is fighting wood hard in the
manufacture of boxes, buckets and even
packing cases, and so perfect is the
manufacturing process that in many in
stances nothing but the wonderful diff
ference in weight can afford clue to
the presence of paper in the manufac-
ture. Paper packing cases are indie
structible, apparently. and the saving
they effect in freight is enormous,

"A writer in the Chemical News says
"While analysing qualitatively mix
ture containing iodides and bromides, il
occurred to me, as my starched paper
was gone, and l was disinclined tc
break off my work to make more, that
might find an efficient substitute ii
ordinary white writing paper. l triet
this, after moistening with water, ant
found to my delight that it did as wei
as the best starch-paper that ever was
prepared; and why not, seeing that, il

paper-or, indeed, any common paper
is finished with size, which contains ,
notable quantity of starch?"
