JENCKES, or JENKS, Joseph, inventor, was born in Wolverton, Shroi^shire, England, in 1602; son [probably] of Francis and Frances (Westfall- ing) Jenckes. When Robert Bridges took speci- mens of iron ore to England from the colonies and told of the great need of iron tools by the colon- ists, he procured the foundation of a comjDany to develop the working of the ore. Joseph Jenckes was induced to come to America as master-me- chanic to establish works in Saugus, Mass. He superintended the construction of the first fur- naces and moulds, and the manufacture of the first domestic utensils, machinery and iron tools on the Western continent and introduced the idea of patenting inventions in America. He re- ceived from the general court of Massachusetts, May 6, 1646, patents " for the making of engines for mills to go with water," for the making of scytlies and other edge-tools, and a new inven- tion for a saw mill, for which lie patented an im- provement in May, 1655. He cut the dies used
in the manufacture cf the " Pine Tree" coins at
the mint established by John Hull in Boston in
1652, which were the first coin issued in America.

scythe, but little niodified for two hundred and fifty years, came into use all over the world. He obtained the government's aid to enable liim to erect machinery to be used in wire-drawing in 1667. He died in Saugus, Mass., March 16, 1683.
JENCKES, Joseph, manufacturer, was born in Buckinghamshire, England, in 1632; son of Joseph Jenckes. His father was the inventor of the grass scythe, and a manufacturer of edge- tools. In 1648 he followed his father to Saugus, Mass., and was connected with him in- the iron and brass works there, the first established in America, On account of the large amount of charcoal needed for smelting and refining iron ore, the forests around Lynn were rapidly becom- ing extinct, which caused much alarm among the manufacturers. Jenckes, in order to establish himself in the iron business, followed Roger Williams to Rhode Island, and Avas granted land in Warwick, in 1669. He purchased a tract of woodland at Pawtucket Falls, near Providence, on the Blackstone river, in 1671. Iron oi-e was discovered near the falls, and Jenckes built a foundry and forge, which were destroyed during King Philip's war in 1676. He rebuilt the works and laid the foundation of the great iron works of Providence. He was the founder of Paw- tucket, R.I. In 1661 he was elected a member of the governor's council, and served as assistant, or lieutenant-governor, and subsequently was a member of the house of deputies. He married Esther Ballard, of Lynn (born in England, 1633), and they had six daughters and four sons. His son Joseph became governor of Rhode Island. He died in Pawtu(!ket, R.I., Jan. 4, 1717.
JENCKES, Joseph, governor of Rhode Island, was born in Pawtucket, R.I., in 1656; son of Joseph (the founder of Pawtucket) and Esther (Ballard) Jenckes. He was a land survej'or, and in this capacity was employed by the Rhode Island colonial government in the boundary dis- putes with adjoining colonies. He was said to liave been of remarkable stature, measuring seven feet and two inclies in lieight. He was elected to the general assembly in 1679, was clerk and speaker of the assembly until 1693, was commissioned to reply to a letter of the King as
