Tempering Pocket Knives 
Will you give me a solution for tem¬ 
pering pocket knives? c. D. B. 
Fort Johnson, N. Y. 
Pocket knives, as well as other steel 
articles are tempered by heat and quick 
cooling. We know of no solution which 
will do it, as the “temper” appears to be 
a special arrangement of the particles of 
the steel. If the blade is heated fairly 
hot and plunged deep into a cake of laun- 
dry soap you may get a fairly good tem¬ 
per. But it is considerable of au art, 
and requires much practice. 
Writing on Zinc Labels 
Borne years ago, I think, I read in The 
R. N.-Y. that by writing with a lead 
pencil on zinc and applying vinegar or 
an acid of some kind the writing becomes 
plain and indelible, and makes a good 
marker for use in orchard or garden. 
Can you inform me what the formula is? 
Providence, It. I. J. k. h. n. 
We do not recall the item, and the 
method you quote seems plain enough for 
a trial, at any rate. But a simple experi¬ 
ment. showed that the process with the 
lead pencil at hand did not work very 
well. Perhaps if a softer pencil with 
larger lead had been used, the effect might 
have been better. What did work very 
well indeed was a “grease pencil,” the 
sort used for marking packages and boxes. 
This protected the zinc for the hour the 
acid was applied, and after washing it off 
the rest of the ziue was eaten away just 
a little bit. and the written part remained. 
Good vinegar will work. Probably a label 
of this sort would last several years. The 
very best scheme, however, is to write 
on zinc with a 10 per cent solution of 
platinum chloride. This is a pretty ex¬ 
pensive ink just now, but not much is 
needed. The writing must be done with 
a quill pen or sharpened stick, or some¬ 
thing of that sort. Any metal pen will 
spoil the job. 
Drilling Out Mortar 
We have recently moved, and would 
much like to change the stovepipe hole 
from the side to the front of a chimney, 
but know of no way to remove the brick 
and mortar excepting by the slow, labor¬ 
ious process of chiseling them out. It 
seems to me there should be something 
one could apply to soften the bricks ami 
mortar so that they can be removed 
easily, and if so, I am sure that some one 
of your many readers will know just 
what it is, and I trust will be glad to 
help a fellow subscriber. As for me, a-nd 
my husband, and that comprises our 
whole family, we think more of The It. 
N.-Y. every issue we receive, mbs. f. s. 
You are not likely to find any good sub¬ 
stitute for the old-fashioned plan of drilling 
through the brick wall with a chisel. If 
it were possible to soften or dissolve the 
brick and mortar easily the chimney 
would be in danger.

Improving Carburetor 
Could you tell me whether I can get 
any make of carburetor for a Ford car 
that is any better than the one put on 
th(> machine when it is sent from the 
works? I have been told there are dif¬ 
ferent ones that are better, also that they 
run on less gasoline. Can you tell me 
of any? Is a spark iutensifier any good 
on a Ford? f. j. c. 
Saegerstown, Pa. 
The makers of various carburetors make 
large claims, but the chances are that you 
cannot bettor yourself by changing till 
you thoroughly understand the one that 
came on the car. So much depends on 
the adjustment by the needle valve that 
you have to work out the best position 
of this for the kind of gas you use, and 
then stick to that kind and the proper ad¬ 
justment. We doubt if a spark intensi- 
fier is needed if the car is doing fairly 
well; if it is not, better have the magnets 
examined, and, if need be, remaguetized. 
Tainted Cistern Water 
Our large cisteru is nearly full, and we 
dare not draw it off. but the water has 
color and odor. What can we do? 
MBS. b. c. ir. 
First of all, make as sure as you can 
that no small animal has died in it. Even 
a very small moiu.o can produce an as¬ 
tonishing amount of odor. If you find 
anything of this sort, you must empty 
the cistern. But rain water sometimes 
gets a stale taste from leaves and lack 
of air. The best thing is to air it well, 
which can be done with a tin can on a 
long polo, pushing it down full of air and 
releasing the air at the bottom by turning 
the pole. But you will have to stick to 
it; it will take several hours. There is 
a pump made which takes down air in 
the buckets and keeps the water well 
aired. If you must ise a “chemical,” 
better put in, with g.iod stirring, about 
four ounces of permanganate of potash. 
Fresh-burned charcoal will often help 
some, and a teacuptu] of chloride of lime 
will work well, but will, of course, harden 
the water a little. 
**. . . places far apart arc brought together, to the present convenience and advantage

From Charles Dickens’ Preface to Pickwick Papers. 
The Advance 
of Understanding 
Even romance of sixty 
brief years ago could not 
imagine the great advance 
heralded by the passing of 
the stage coach. The rail¬ 
way and telegraph were 
coming into their own; but 
the telephone had not been 
so much as dreamed about. 
Yet the wise men of that 
day saw the imperative 
need. They saw the value 
of every step which 
, brought people into closer 
communication with each 
other. They knew this to 
be the one way to increase 
understanding; and to 
eliminate the “host of petty 
jealousies, blindnesses and 
prejudices, by which the 
Public alone have always 
been the sufferers.” 
Then came the tele¬ 
phone. And with its com¬ 
ing time and distance are 
swept away and a hundred 
million people are made 
neighbors.

fying book she has read in many a day.”
