Part 1 (2/2)
The answer to this is, that the student of to-day has the advantage of the knowledge of all who have gone before; and now the pertinent thing is to acquire that knowledge
THE MEANS EMPLOYED--This brings us definitely down to an examination of the e, so that it may become a permanent asset to the student's store of infor in the history of electrical developreat scientists not one of thee to the science on purely speculative reasoning All of them were experimenters They practically applied and developed their theories in the laboratory or the workshop The natural inference is, therefore, that the boy who starts out to acquire a knowledge of electricity, must not only theorize, but that he shall, primarily, conduct the experiments, and thereby acquire the information in a practical way, one exaes of dry text
Throughout these pages, therefore, I shall, as briefly as possible, point out the theories involved, as a foundation for the work, and then illustrate the structural types or saed that what is done to-day is -stone to the next phase of the art In reality, we shall travel, to a considerable extent, the course which the great investigators follohen they were groping for the facts and discovering the great manifestations in nature
CHAPTER II
WHAT TOOLS AND APPARATUS ARE NEEDED
PREPARING THE WORKSHOP--Before co actual experioing into this work as pioneers, we shall have to be dependent upon our own efforts for the production of the electrical apparatus, so as to be able, with our home-made factory, to provide the power, the heat and the electricity
Then, finding we are successful in these enterprises, we may look forward for ”hbors will become interested in and solicit work from us
USES OF OUR WORKSHOPS--They may want us to test batteries, and it then becomes necessary to construct mechanism to detect and measure electricity; to install new and improved apparatus; and to put in and connect up electric bells in their houses, as well as burglar alarraph line, having learned, as well as we are able, how they are raph too slow and altogether unsuited for our purposes, as well as for the uses of the neighborhood, so we conclude to put in a telephone system
WHAT TO BUILD--It is necessary, therefore, to coht at the bottom to build a telephone, a transmitter, a receiver and a switch-board for our syste into touch with the great outside world, and wireless telegraphy absorbs our tiies
But as we learn s electricity will do, we are brought into contact with problems which directly interest the home Sanitation attracts our attention Why cannot electricity act as an agent to purify our drinking water, to sterilize sewage and to arrest offensive odors? Weabout the subject of electrolysis
WHAT TO LEARN--The deco that we shall describe pertaining to this subject We go a step further, and find that we can decompose metals as well as liquids, and that we can make a pure metal out of an impure one, as well as make the foulest water pure But we shall also, in the course of our experiments, find that a cheap metal can be coated with a costly one by means of electricity--that we can electroplate by electrolysis
USES OF THE ELECTRICAL DEVICES--While all this is progressing and our factory is turning out an a variety of useful articles, we are led to inquire into the uses to which we may devote our surplus electricity
The currentsad-irons, as well as for other purposes which are daily required
TOOLS--To do these things tools are necessary, and for the present they should not be expensive A sidly built bench is the first require 1, of three 2-inch planks, each 10 inches wide and 6 feet long, ht In the front part are three drawers for your material, or the small odds and ends, as well as for such little tools as you may accumulate Then you will need a small vise, say, with a 2-inch jaw, and you will also require a hand reel for winding nets This will be fully described hereafter
You can also, probably, get a sreatest service in your work It should be mounted close up to the work bench Two small hammers, one with an A-shaped peon, and the other with a round peon, should be selected, and also a plane and a small wood saith fine teeth A bit stock, or a ratchet drill, if you can afford it, with a variety of small drills; tood chisels, say of 3/8-inch and 3/4-inch widths; small cold chisels; hack saw, 10-inch blade; small iron square; pair of dividers; tin shears; wire cutters; 2 pairs of pliers, one flat and the other round-nosed; 2 awls, centering punch, wire cutters, and, finally, soldering tools

If a gas stove is not available, a brazing torch is an essential tool
Nuiron, with pointed end, should be provided; also imlets; a screwdriver; pair of pliers and wire cutters
Fro it will be seen that the cost of tools is not a very expensive item
