The Hours of each Day are to be divided and dispos'd in such a Manner, as that some Classes may be with the Writing-Master, improving their Hands, others with the Mathematical Master, learning Arithmetick, Accompts, Geography, Use of the Globes, Drawing, Mechanicks, &c.; while the rest are in the _English_ School, under the _English_ Master's Care. Thus instructed, Youth will come out of this School fitted for learning any Business, Calling or Profession, except such wherein Languages are required; and tho' unacquainted with any antient or foreign Tongue, they will be Masters of their own, which is of more immediate and general Use; and withal will have attain'd many other valuable Accomplishments; the Time usually spent in acquiring those Languages, often without Success, being here employ'd in laying such a Foundation of Knowledge and Ability, as, properly improv'd, may qualify them to pass thro' and execute the several Offices of civil Life, with Advantage and Reputation to themselves and Country. B.F. TO C[ADWALLADER] C[OLDEN] ESQ. AT NEW YORK Communicated to Mr. Collinson [Philadelphia] 1751. SIR, I inclose you answers, such as my present hurry of business will permit me to make, to the principal queries contained in yours of the 28th instant, and beg leave to refer you to the latter piece in the printed collection of my papers, for farther explanation of the difference between what are called _electrics per se_, and _non-electrics_. When you have had time to read and consider these papers, I will endeavour to make any new experiments you shall propose, that you think may afford farther light or satisfaction to either of us; and shall be much obliged to you for such remarks, objections, &c., as may occur to you. I forget whether I wrote you that I have melted brass pins and steel needles, inverted the poles of the magnetic needle, given a magnetism and polarity to needles that had none, and fired dry gunpowder by the electric spark. I have five bottles that contain 8 or 9 gallons each, two of which charg'd, are sufficient for those purposes: but I can charge and discharge them altogether. There are no bounds (but what expence and labour give) to the force man may raise and use in the electrical way: for bottle may be added to bottle _in infinitum_, and all united and discharged together as one, the force and effect proportioned to their number and size. The greatest known effects of common lightning may, I think, without much difficulty, be exceeded in this way, which a few years since could not have been believed, and even now may seem to many a little extravagant to suppose. So we are got beyond the skill of _Rabelais's_ devils of two years old, who, he humorously says, had only learnt to thunder and lighten a little round the head of a cabbage.[38]
