Mr. G. ('. Walworth was born in New Hampshire in 1816, where he had the usual school and academy chances for an education. This with teaching employed his time till of age. In 1836 he went West, and remained for several years, returning to be married in 1846. He was prosperous in agricultural matters, and accumulated a property which has since sold for over $100,000.

The next spring he engaged with Walworth & Nason in the business of steam heating. After three years, or in 1850, he took charge of the manufacturing department. Soon after this he invented and patented some very fine machines. The six-spindle tapping machine is here illustrated. With these machines about ten times the amount of work could be accomplished, and better than before. Besides l>eing an inventor of the first order and a successful financier, he is one of the best men to handle labor; he has avoided all strikes and labor troubles; the men, finding that they are justly treated and promptly paid, have little cause for complaint. He became general manager in 1881.

Mr. Walworth has made many other valuable inventions in the line of his business, among which is his patent radiator; a manifold, which reduces the cost over the old-fashioned fittings and gives perfect control of the use of the steam; the patent screw plate, which to-day is the screw plate of the world, there being a large demand for them abroad; also a patent safety floor flange. In connection with Mr. O. 11. Hall, he invented the Walworth Sprinkler, which has saved millions of dollars -£. worth of property. See last page of Volume I.

Besides his own contributions to the mechanic am. he has aided and stimulated others to make inventions of useful and valuable took. The Stillmn Wrench was one of these, and to the inventor the company have paid large sums in the way of royalty; while the well-known Chapman Valve was worked out at the factory in Cambridgeport. and had merit enough to succeed and float a stock company.

He early foresaw the necessity of having a foundry for casting malleable iron, and obtained a bond for a deed of the Malleable Foundry at Bradford, where he organized a company called the Malleable Iron Fittings Co. Mr. E. C. Hammer was chosen president.

The patents for the tapping machine were put in for $50.000; the balance was ¥75.000, making the company's capital *125.000.

All of Mr. Walworth's inventions were valuableo and gave quick returns. These profits he reinvested in shares of the company, so that in 1883 he had acquired a controlling interest, when there was a change of officers and directors, resulting in the present Board.

The rapid increase of the business of the Walworth company called for better and more extensive accommodations, resulting in the purchase of the Crystal Glass Works, at South Bostou Point, containing some ten acres; four acres of the upland are fully used for the business. On this property is a fine store wharf, which is a saving of a large amount of freight. All coal, sand, and iron being landed above are dropped down through the roof into the bins where they are to be stored, and the iron simply carted to the cupola. This will melt forty thousand pounds of iron each day, and is used entirely in the business, the company doing no work for outside parties. There is a very fine foundrv, with railroad to carry the iron when melted, saving the men much hard work, besides being able to do much more work for the same number of men. The buildings on this property had to be changed to meet the new business, and a new building four hundred and twentyfive feet long by sixty feet wide. (See last page of Vol. 1.)

Mr. Walworth is a remarkable man: although at this writing in his seventy-fifth year, he is in the enjoyment of good health, and carries the interests of his large and still growing company.

Having lost in 1887 perhaps the best wife that ever blessed a mortal's home on earth, he sorrowed long without hope, until it pleased the Father to reward his faith and show him a ray of light—"a silver lining to the cloud." This was a lady, also bereaved of her first and natural protector; what more natural and fitting result than that they should agree to comfort and cheer each other's lonelv and remaining years? In short, they were married Nov. 14, 1889, and soon after, in truly youthful style, took the Pullman train to a land of winter fruits and flowers.
