"At that time and even after the great fire in 1889, Yesler Avenue was known as Mill Street, the name having originated from the fact that Yesler's mill was located at its foot. Where the magnificent Dexter Horton bank building now stands stood a small wooden structure occupied by Dexter Horton as a store, and where the National Bank of Commerce building, at the corner of Yesler Avenue and Commercial Street, stood the mill store of the Yesler-Denny Company. S. B. Hinds, a name forgotten in commercial circles, kept store on Commercial Street, between Washington and Main Streets. Charles Plummer was at the corner of Main and Commercial, and J. R. Williamson was on the east side of Commercial Street, a half block north. This comprised the entire list of stores at that time. The forests were the only source to which the settlers looked for commercial commodities, and these, when put in salable shape, were often-times compelled to await means of transportation to markets. Briefly summed up, spars, piles, lumber and hop-poles were about all the sources of income. "At that time there was no 'blue book,' and, in fact women were scarce. It is not surprising then that the arrival of William Casto, a man aged 38 years and a true representative of the Kentucky colonel type, with his young wife, the daughter of John Bonser, of Sauvies Island, Columbia River, near Portland, should have been a memorable occasion. Mrs. Casto was a natural not an artificial beauty--one of those women to whom all apparel adapts itself and becomes a part of the wearer. Every movement was graceful and her face one that an artist would have raved about--not that dark, imperious beauty that some might expect, but the exact opposite. Her eyes were large, blue and expressive, while her complexion, clear as alabaster, was rendered more attractive by a rosy hue. She was admired by all and fairly worshipped by her husband. It was one of those rare cases where disparity in ages did not prevent mutual devotion. "In the spring of the year that Casto came to Seattle he took up a ranch in the heart of Squak valley, where the Tibbetts farm now lies. Here he built a small house, put in a garden and commenced clearing. In order to create an income for himself and wife he opened a small trading post and carried on the manufacture of hoop poles. The valley was peculiarly adapted to this business, owing to the dense growth of hazel bush, the very article most desired.
