THE YOUNG SCIENTIST. 
you can secure any subscriptions, our 
premium list affords a great variety of 
opportunities for procuring something 
that you want. Tlie great obstacle in the 
way of the success of a small paper of the 
special character of the Young Scientist 
is the expense of advertising. Therefore, 
we must rely largely upon the kind offices 
of our readers to make the journal known 
to others. So much, then, for hopes and 
-expectations for the coming year. In the 
hope that it will be a successful one for 
us and a pleasant one for you, we wish 
you 
A Merey Christmas and a Happy New 
Year.

BOOK NOTICES. 
Xectures in a Workshop : By T. P. Pember- 
ton, formerly Associate Editor of the " Tech- 
nologist ; " Author of The Student's Illustrated 
Guide to Practical Draughting." With an ap- 
pendix containing the famous papers by Whit- 
worth " On Plane Metallic Surfaces or True 
Planes:" "On an Uniform System of Screw 
Threads;" "Address to the Institution of 
Mechanical Engineer's, Glasgow;" ' On Stand- 
ard Decimal Measures of Length." $1.00. New 
York: Industrial Publication Co. 
The volume before us consists of a series of 
lectures and articles specially addressed to young 
mechanics. Several of these lectures were de- 
livered before the Polytechnic Association of the 
American Institute, and were received with very 
great favor. The whole has been carefully re- 
vised and the unavoidable repetitions of an UD- 
connected series having been cut out and other 
•and more valuable points enlarged. The collec- 
tion no\v torms a sprightly, fascinating book, 
lull of valuable hints, interesting anecdotes and 
sharp sayings. It is not a compilation of dull 
sermons or dry mathematics, but a live, readable 
book. The papers by Whitworth, now first made 
accessible to the American reader, form the basis 
Df our modern systems of accurate work. 
The Boston Journal of Chemistry and Popu- 
lar Science Keview: Devoted to Chemistry, 
Pharmacy, Geology, Agriculture, Astronomy, 
Hygiene, Medicine, Practical Arts, Home 
Science, etc., etc. $1.00 per year. Boston: 
Journal of Chemistry Company, 
This valuable journal has come to our desk 
regularly during the past year, and is always read 
with interest. It has recently enlarged somewhat 
the range of subjects which it discusses, and is 
now one of the very best exponents of general" 
scientific progress. It gives brief notes of almost 
all scientific discoveries, and the care with which 
it is edited and the low price of its subscription 
commends it to those who wish to keep posted, 
but whose time for scientific study is limited. 
The Builder and Wood Worker: A Journal 
of Industrial Arts. Published Monthly at 176 
Broadway, New York. Chas. D, Lakey. Pub- 
lisher. Fred. T. Hodgson. Editor. 
The December number completes the seven- 
teenth volume of this sterling periodical, which, 
under the able editorship of Mr. Hodgson, has 
now reached a circulation of which even sensa- 
tional journals might be proud. The numbers 
which have reached us regularly during the year 
have been characterized by sound good sense, 
thorough knowledge of the arts which they dis- 
cuss, and perfect ability to make matters clear 
to even the dullest workman. The illustrations, 
of which there is every month several full pages 
of detail drawings, are alone worth far more than 
the small price— $1.50— asked for the journal. 
Those who desire to club the Builder and Wood 
Worker with the Young Scientist can have both 
journals for $1.50. 
Protect the Birds. 
Ed. Young Scientist — Now that the winter 
has arrived and the ground w^ill soon be covered 
with snow, it would be a good idea for the read- 
ers of the Young Scientist and their friends, 
both boys and girls, to scatter food to the poor 
little birds, who are unable to obtain food for 
themselves ; and I am sure any boy or girl who 
follows the above suggestion will be amply re- 
paid at the end of winter to think that they 
may have saved the lives of the little birds, who 
will then reward them by their lively song. But 
while talking about protecting the birds, I 
would like to suggest that for the coming year 
(1882) a society should be formed called "The 
Society for the Protection of Birds." If this 
suggestion meets with the favor of the editor, 
I should like to hear from the boys and girls 
themselves through these columns.
