THE YOUNG SCIENTIST. 
teams representing New York and Phila- 
delphia and interstate malches during 
the month of September. Before the wa,r 
it was a common thing to see the States 
of New York and Massachusetts, or New 
Jersey and Pennsylvania measuring bats, 
and a series of interstate contests at this 
particular time would do more to popu- 
larize cricket than any other series of 
games that could be thought of. 
When boys— or girls either, for that 
matter — undertake to make or do any- 
thing that requires skill or thought, they 
should " make haste slowly," by doing it 
systematically, coolly, and deliberately. 
If amateur work is undertaken methodi- 
cally, and free from excitement or undue 
eagerness, it is surprising how much 
more may be done, and how much better 
done it is. And then there is no unneces- 
sary wear and tear of strength, no lost 
effort, and everything is more likely to go 
along smoothly. While at work, all the 
faculties should be concentrated upon it, 
for it is impossible to do good work while 
the hands are performing one service and 
the mind another. It was a shrewd ob- 
servation of Kirke White, the gifted poet, 
whose early death adds a touch of melan- 
choly to all he wrote, that he found, if he 
concentrated his whole attention on the 
-dryest book he had to study, it soon be- 
came interesting, and in a short time he 
v^ould become so absorbed as to turn over 
page after page unconsciously to himself. 
Intensity of thought is not exhausting if 
not too long continued: so that in one 
;sense he who works the hardest accom- 
plishes his task more easily. He has also 
much more time for rest and recreation. 
When at work, there should be as little 
interruption as possible, as these are apt 
to divert the mind into channels not re- 
lated to the work in hand. Whatever 
may be the character of the work in 
hand — scientific, artistic, or mechanical — 
the surroundings should be as cheerful as 
] possible, and with these conditions, if the 
worker is self-possessed and cheerful by 
nature, the work, no matter how hard it 
may be, will appear to be easy and 
pleasant. 
A Dictionary of Useful Animals and their 
Products. A Manual of Eeady Reference for 
all those which nve Commercially Important, 
and others which man has utilized, including 
also a Glossary of Trade jnid Technical Terms 
connected therewith. By P. L. Simmonds. E. 
& F. N. Spon, Publishers. New York and 
London. 
To students, and those interested commercially 
in fabrics, and other goods made from animal 
products, this little book will prove very useful, 
as it contains a great deal of information relative 
to these matters. Being a dictionary, the subjects 
are alphabetically arranged, and are easily found. 
So that the reader may have an idea of the work, 
we quote an item or two : 
"Beak^ Ursus), a well-known animal, of which 
there are several species. It is hunted chiefly for 
its skin, which is used for sleigh robes and wrap- 
pers, saddle housings and rugs. From 8,000 to 
10,000 are received annually in England, but in 
the early part of this century nearly three times 
that number were imported. The flesh of nearly 
all bears is edible, but some is not very palatable. 
The long claws of the grisly bear are strung as 
necklaces, and highly prized as trophies of 
prowess among the Indian braves, who pride 
themselves excessively upon the number of bears 
they have succeeded in destroying." 
"MooNGA, OK MooGA SiLKWoKM ( Anther oBa as- 
sama, Heifer). The cocoons are soft and of a 
light fawn color. They furnish an excellent raw 
silk, of which there is a large consumption in 
British India. This silk forms one of the prin- 
cipal exports of Assam, and leaves the country 
generally in the shape of thread." 
The book is well printed, and neatly and 
strongly bound. 
Practical Carpentry. Being a guide to the 
correct working and laying out of all kinds of 
Carpenters' and Joiners' work. With the solu- 
tions of the various problems in Hip-Roofs,

and Jointing, Hinging, Dovetailing, Mitering,

Geometry." By the author of " The Steel Square 
and Its lises," " The Builder's Guide and Esti- 
mator's Price Book," " The Slide Eule and How

This is the most complete book of the kind ever 
published. It is thorough, practical and reliable, 
and at the same time is written in a style so plaii: 
that any workman or apprentice can easily un- 
derstand it, and for those of our readers who are 
fond of working in wood, it offers many hints 
and suggestions of a kind that every successful 
amateur must know. The work is published by 
the Industrial Publication Co., 294 Broadway, 
New York, and is sold at a price (one dollar) that 
places it within the reach of every one. ft is 
illustrated by over 300 engravings, well printed 
ou flue paper, and bound in a durable mauuci'.
