In 1851, Mr. Coe organized and got into operation the Commercial Mutual Insurance Company, of this city, acting as its Secretary for about one year and a half, when he resigned, and went into the insurance agency business, with which he has ever since been identified. In 1865, Mr. Henry F. Clark desired him to reorganize the Cleveland Insurance Company, the charter of which was granted by the State of Ohio in 1830, and which was successfully managed by his father, Mr. Edmund Clark, until his death. Mr. Coe undertook and completed the task, and operations re-commenced April 1st, of the same year, on a paid up cash capital of one hundred thousand dollars, increased in 1866, to one hundred and fifty thousand; and in 1867, to two hundred thousand dollars, and now increased to its limit, five hundred thousand dollars, making it the largest cash capital company in the State of Ohio, a credit to the city and to the State at large. Mr. Coe is the right man in the right place, as the successful workings of this company fully demonstrate. He, as secretary, devotes his whole attention to the interest of the company. H. B. Payne is the president, and S. D. McMillan, vice-president. In looking over a correspondence of about twenty years ago, in search of some data connected with Mr. Coe's history, we came on the following letters, which will be read with amusement by old Clevelanders, as reminiscences of the ante-railroad period, and for the allusions to public and political events of that day, as well as for the contrast between the irascible tone of one letter, and the cool humor of the other: Messrs. S. S. Coe & Co., Cleveland, Ohio: Gentlemen,--No one dislikes, more than we do, to grumble or find fault, but we hate just as bad to have our boats detained beyond a reasonable time, at your place; and when our boats leave here for your place, we look for them back at a certain time; and if they do not get here soon after that time, it disarranges all our calculations and proves a great loss to us. All our boats were detained a week on account of a break in our canal, and then to be detained beyond a reasonable time in port, makes it worse. Mr. Wheeler, at Akron, is the only man on the Ohio canal, that we know of, that has been in the business longer than we have on our canal, and we defy you to find a boatman on our canal or river that will say we ever detained them beyond a reasonable time; and there is no need of it if men do as they would be done by, and the situation our river has been in this geason has been vexatious enough for any one. Time is money, and eight or ten boats being detained a day or two counts up. The J. Larkin left for your place to-day. Tours truly, S. Adams & Co. Cleveland, July 29th, 1848. Messrs. Sam'l Adams & Co., Dresden, O.: Gentlemen,--Your esteemed favor of the 25th inst. is at hand.
