Important Notice. 
THIS number of the Young Scientist is 
sent as a sample to all our old sub- 
scsibers and to many who have never 
taken the journal. It is unnecessary for 
us to intimate that we would be glad to 
have all who see this number send us their 
subscriptions, but it may be well to say 
that no bills are sent out for the Young 
Scientist, and no credits given. When a 
subscription expires the journal is 
stopped. Our reason for this course lies 
in the simple fact that the price of the 
journal is so low that it is impossible for 
us to keep book accounts and send bills. 

Who Wants a Rifle? 
TI/'E have a very fine little Flobert rifle, 
' " the bore of which has been rifled so 
that it shoots with great accuracy. (The 
ordinary Flobert rifles are all "smooth 
bores.) It is just the thing for small game 
or target practice, and we will give it to 
the first that sends us a club of fifty sub- 
scribers to the Young Scientist. Eemem- 
ber, this weapon will be given to the first 
that completes a club of fifty ; after that, 
those who wish a rifle as a premium, will 
have to be satisfied with the ordinary 
weapon. 
1882.— To Our Readers. 
WITH this number the Young Scientist: 
enters upon its fifth year. In noting 
the addition of another volume to the 
series, we cannot help acknowledging the 
appreciation which our efforts have re- 
ceived, and assuring our readers that their 
kind words and efforts have not passed 
unheeded by us. We could each month 
fill one or two pages with extracts from 
commendation letters that we have re- 
ceived, but we have always preferred to- 
occupy our limited space with matter of 
more immediate value to our subscribers. 
Our arrangements for 1882 are such that 
we feel assured that the fifth volume will 
be better than any that has preceded it. 
Prof. Wright will give us each month a 
series of interesting notes on astronomy. 
Mr. Hodgson will continue his thoroughly 
practical articles ; the " Marvels of Pond 
Life " will, as the summer advances, in- 
crease in interest and in the wonders 
which they develop; and we have en- 
gaged a series on the aquarium, the lathe, 
glass working, the voltaic battery, scien- 
tific experiments, etc. We hope also to 
be able to give the best series of articles 
on boat- building that has ever appeared. 
There are other interesting and important 
subjects in regard to which we have 
corresponded with w^riters who are able 
to give us good and popular articles. 
Amongst these is a monthly 7^esume of the 
scientific progress of the world. Such 
a series might, we think, give our young- 
people, and even some of our older ones, 
a valuable hint, at least of all the most 
important discoveries. 
How far we shall be able to make the 
Young Scientist for 1882 equal to what we 
would like it to be, remains to be seen. 
We shall faithfully do our best, and we 
hope to receive aid from every one who 
has enjoyed reading our paper. 
And now, reader, let us suggest a 
method by which 3^ou can aid us materi- 
ally in the improvement of your journal 
and ours. It is simply by calling the at- 
tention of all your friends to the Young 
Scientist. If any of your numbers are 
injured by so lending or showing them, 
we will cheerfully replace them, and if
