Afar off westward, the uplands wore a tinge of tenderest blue; and in the nearer distance, on the low shores of the river, superb summer residences, tasty villas, and elegant hotels, built in every style of architecture, lay interspersed between romantic hills and tufted groves. The horizon was of a fine, golden tint, changing gradually into the deep blue of the mid-heaven. None of us ventured to leave the deck fearing to miss some of those unrivaled sights constantly offering new attractions. This trip on River St. Clair--though having an extent of thirty-three miles--seemed but short to us; and the fine spectacle displayed on the charming western bank may be reckoned among the most delightful scenes we beheld on our long, enjoyable voyage. As we approached the terminus of the river, a sudden rush of the awakened wind was heard; and out of the blue horizon a troop of narrow, dark, and pointed clouds were advancing, covering the sky, inch by inch, with their gray masses gradually blotting the light out of the landscape. Horizontal bars of black shadow were forming under them, and lurid wreaths wrapped themselves about the crests of the hills. The wind had grown more violent as _Port Huron_ came in view. Waving curtains of opaque rain, swinging from the overburdened clouds, dropped down upon the surface of the river. The black swaying fringes, sweeping irresistibly along the water, churned the surface into foam. The sudden and unfavorable change of the weather determined our commodore to abide at _Port Huron_, a prosperous city in Michigan. It commands a very advantageous situation, located on the west bank of River St. Clair, and at the southern extremity of Lake Huron. Being the county seat of St. Clair County, it is also a point of great importance in the railway system, and the terminus of several lines of lake steamers. The city, with a population of nearly 14,000, has a large lumber trade, ship-yards, dry-docks, saw and flour mills. Founded in 1819, Port Huron was incorporated as a village in 1835, and as a city in 1857. Since the yacht lingered here until Monday, August 7th, we were enabled to become familiar with its broad streets, regularly laid out and well shaded; some adorned by beautiful private residences. The heavy, black clouds that had shrouded the whole sky ever since we made our entry in Port Huron, were yet concealing the golden disk of the summer sun. The atmosphere, however, which had previously a disagreeable, wet chilliness in it, gradually grew clearer and warmer so that we left the dock with the intention to undertake our voyage on Lake Huron, but when nearing the place where this sheet of water, covering an area of 23,000 square miles, communicates with River St. Clair, we discovered that the swell on the lake level was yet quite considerable, whereas the wind which had blown a gale all the preceding day, was gradually dying away.
