Market Street is the principal one. It is a noble thoroughfare, at least twice the width of Broadway in New York, with trees on either side, and very wide pavements. The buildings, mostly stone, cast into the shade anything we can show in London, and nowhere on the Continent have I seen such a main artery to any town. The Palace Hotel in it is by far the largest and finest in America, and even those we have here in Northumberland Avenue are more or less small in comparison. It is an enormous, very lofty quadrangle, with inner verandahs on each story, built round a spacious court, which is glazed in at top of the building. I forget how many hundred bed-rooms it contains. The interior is also a model of luxury and comfort. In every department money has been lavishly spent, and the result is that the Palace Hotel is possibly the largest and best in the world. The charges also, considering the comforts offered, are by no means high. I believe it was built by one man out of the enormous fortune he accumulated in the first gold days, but what is the result of the speculation I could not ascertain. There is a large and very beautiful park outside the town. Trees, shrubs, and flowers from all parts of the world are collected therein, while for those that require tropical temperature huge glass buildings are provided. All testifies to a luxurious growth, and the smooth, closely-shaven, mossy grass is of a picturesque bright emerald green. It is all artificial! Neither grass, shrubs, flowers, or trees would grow at all did they depend on rain alone. Everything is irrigated. Below the surface a network of waterpipes runs in all directions with taps available everywhere. I was much struck by the way the turf is watered. The water is forced with great power through minute orifices in the large splay metal end of a hose, ascends some thirty or forty feet, and falls exactly in the form of very fine rain; thus every blade of grass is moistened. Wonderful indeed is the effect as you stand at the park entrance and compare the scene outside and within. The dry, baked soil, innocent of vegetation on the one hand, the luxurious growth of many lands combined on the other, interspersed with a green sward you long to fling yourself down and roll on!
