It is worthy of remark, however, that even though nature is his theme, the poet writes rather as an interested spectator than as an earnest votary. He reveals no passion for the landscapes he depicts. He never appears as if himself a portion of the scene, alive with sympathy in all the varying moods of nature. His verse has no flashes of inspiration, such as contact with storm and spate drew from Burns. It was already, however, a great achievement that Thomson broke through the conventionalities of the time, and led his countrymen once more to the green fields, the moors, and the woodlands. In the successive poems which when placed together made the _Seasons_, published in 1730, Thomson continued to draw on his recollections of the Scottish Border for the descriptions of landscape that form so fundamental a part of his theme. It is interesting to note that even after he had been five years in the south of England, and must have seen in that time much variety of weather and many different watercourses, it is still from the north that he draws his sketches. When, for instance, he tells how in autumn, 'Red from the hills, innumerable streams Tumultuous roar,'[33] the colour of his torrents betrays their Scottish origin. He was thinking of the spates in his native streams which sweep across tracts of Old Red Sandstone, and come down almost brick-red in hue. There are no red rocks, and therefore no red brooks in Middlesex and the surrounding districts. But before the completion of the _Seasons_ the influence of English lowland scenery had begun to impress itself on Thomson's imagination. The softer and ampler landscape of fruitful plains, with its richer agriculture and fuller population, its farms, villages, and country houses, filled his mind with a new pleasure. Some trace of this widened experience may be seen in the additions successively made to the earlier poems, such as the picture of Hagley Park introduced into the poem on _Spring_. But it was in his last effusion, _The Castle of Indolence_, that this English influence gained entire sway, and the Scottish memories faded into the background. Here we find ourselves amid the typical landscapes of the south of England--landscapes, however, so transfused by poetic genius as to acquire an individuality of their own. We are led into 'a lowly dale fast by a river's side'; we wander through 'sleep-soothing groves and quiet lawns between'; we see 'glittering streamlets' in a sunny glade'; we skirt a 'sable, silent, solemn forest'; and pass a 'wood of blackening pines,' which runs up the hills on either side, and see the famous castle 'close hid amid embowering trees,' that make a kind of chequered day and night. The landscape, we are told, 'inspires perfect ease'--a quality which must now have become indispensable to the 'bard, more fat than bard beseems.' Thomson, with his adoption of English scenery, had also polished his style and rid himself of much of his turgidity and latinism.
