About this time the owners of the Pembroke mill and property connected therewith, in Pembroke and Allenstown, N. H., decided to increase their business by building a new mill twice the capacity of the one then owned by them. Knowing Mr. Jewell to be a good draughtsman, having employed him during the construction of the Pembroke mill, they again engaged him for like duties. Consulting with their then resident agent, he prepared the required working plans and drawings for the Webster mill. The work on the building was soon under way and rapidly pushed to completion. While thus engaged the agent at Newton died, and the immediate care of the mills was given to Mr. Jewell until (as the treasurer said) he could find the right man. Finishing his work at Suncook, and having conducted the affairs of the company at Newton in a very satisfactory manner, the treasurer tendered him the agency of the mills. In accepting the position, his career as agent began where, fifteen years before, he commenced the work that fitted him so thoroughly for the successful management of the same. The mills were in a bad condition, the machinery old, and "run down," and the owners impatient and anxious. Nothing daunted, however, Mr. Jewell entered heartily into the business, making such changes that at the time he tendered his resignation he had doubled the production, and greatly improved the quality of the goods manufactured. Looms built more than fifty years ago, and improved by Mr. Jewell, are still running and producing nearly as many yards per day, and of as good quality, as those made at the present time. These mills were run throughout the war, paying for cotton as high as one dollar a pound, and selling the cloth for thirty-five cents a yard. Mr. Jewell was very anxious to enlist during the exciting times of war, but was prevailed upon by the owners to continue in charge of their works, and by the entreaties of his wife, who was hopelessly ill, to remain at her side. The treasurer and part owner of the mills at Newton Upper Falls was also treasurer and large owner of the mills at Suncook. In 1865 the Suncook company agitated the subject of enlarging their works by the addition of another mill, and in 1867 active operations were commenced upon the China mill, which was, when completed, the largest works of the kind contained under one roof in the state. Mr. Jewell again fulfilled the office of engineer and draughtsman. The company's agent at Suncook, wishing to devote his time exclusively to the construction of the new mill, desired that Mr. Jewell come from Newton several days each week to look after the manufacturing in the two mills. Thus for more than two years he acted as agent at Newton, also as superintendent of the Webster and Pembroke mills.
