In recent years an attempt has been made to reintroduce the salmon into the Thames, and many young salmon have been turned out in the river, but so far without any useful result. But though the salmon has been, and again may be an inhabitant of the Thames, the brown trout is, and always has been, the fish of Berkshire. It attains a large size, and fish of from 8 to 12 lbs. are frequently caught in the Thames. There is, however, a scarcity of suitable breeding-places for trout in the river, and the stock, during recent years, has been kept up by introducing young fish, and not only brown trout but also Lochleven trout and rainbow trout have been turned into the river in great numbers. Many of the tributaries of the Thames are excellent trout streams, the Lambourn being a particularly good one. The pike is found in the rivers and in many a lake and pond throughout Berkshire. Grayling occur in the Kennet and are occasionally caught in the Thames. The gudgeon is a well-known Thames fish; and perch, roach, dace, barbel and minnows abound. The little ruff or pope is fairly common in the Thames, and the miller's thumb, another small fish belonging to the cooler parts of the world, is to be seen in most of our streams darting from place to place with great rapidity. The rudd, which is generally distributed through the more level part of England, is not common in Berkshire. The bream is occasionally caught in the Thames, but it is not a native and was probably introduced from Norfolk. The great variety of soil found in the river valleys, on the chalk downs, and in the forest district gives rise to much difference in the vegetation in different parts of the county. The beds of bullrush, the yellow and purple loosestrife, and the white and yellow water-lily are intimately associated with the beauty of the Thames. The ling, the bell heather, and the cross-leaved heath cover large tracts in the eastern part of the county, and the bilberry is found in the woods of the same district. The bramble abounds in the forest parts, and of cultivated fruits we have large orchards of plums and cherries in the northern part of the county. Some rare orchids are to be found on the chalk, and in the peat districts the interesting little sundew is quite common. In the chalk district the holly and beech grow well, and fine oaks are to be seen in many parts of our county. Herne's Oak, in Windsor Park, has given rise to much discussion, but there can be little doubt that the tree known by that name to Shakespeare was cut down in 1796. There are some avenues of fine elms in Windsor Park--notably the Long Walk.
