Novelties for Amateurs. 
A very ingenious device for attaching small 
hooks to walls has recently been brought out 
by W. H. Hasbrouck, No. 91 Liberty street, New 
York. 
The device consists of a piece of strong paper, 
printed and cut to some appropriate design, as 
shown in the cuts. The paper is covered with 
made, but there are styles such as ivy and 
autumn leaves, and other elegant designs litho- 
graphed in brilliant colors. 
The adhesive hooks can be used in many 
places Avliere tacks or nails cannot be driven at 
all; as on stone or brick walls, metal surfaces, 
glass, etc., and are easily put up, as they only 
require to bo moistened on the back and 
pressed firmly against the wall or other surface 
for a few^ moments, Avhen thoy are ready for use.. 
For light articles, sucli as small pictures,, 
plaques, calendars, match-boxes, almanacs,, 
time-tables, show-cards, brushes, toilet-cases,, 
catch-alls, watches, etc., they are a decided im- 
provoment over nails or tacks, and in no case 
whatever do they disfigure a wall. 
For hundreds of years it has been the custom 
of tlie Egyptians to hatch chickens by artificial 
means; tlie first country in Europe to adopt 
this method on a large scale was France. About 
ten years ago it was introduced into America, 
and now thousands of chickens are hatched in 
incubators in tlie vicinity of N^^w York every 
year. This system has several advantages over 
the old yv{\.y. The time occupied by a hen in 
setting and rearing a brood of chicks is about 
three months; this occurs at the season of the 
year Avhich is most favorable for lajang. Dur- 
ing this time she would probably produce sixty 
or seventy eggs — another advantage being to 
secure early birds for the market, when broilers 
are worth from fifty cents to one dollar per 
pound. There is no occupation more pleasant 
or profitable to boys on farms 
or in villages than rearing 
cliickens. It requires very little 
capital, and the returns in cash 
from sale of eggs and chick<ms 
will make an easily-earned in- 
come. 
Tiiore are several manufac- 
turers of incubators and arti- 
ficial mothers; all are expen- 
sive, ranging in price from $25
