The official correspondence from 1866 to the present time is not very interesting, having reference principally to suggested improvements; it is very bulky, and shows that a large amount of official interest has been taken in the subject; but the money expended and the work accomplished indicate that hitherto Government and Parliament have had but a faint idea of their obligations in regard to the Jenolan Caves. CHAPTER II. THE APPROACH TO THE CAVES. There are several routes to the caves. That commonly chosen is by way of Tarana, a small township 120 miles from Sydney by rail, and 2,560 feet above the level of the sea. The train journey is through interesting country. Leaving behind the new western suburbs with their elegant villas, stately mansions, and well-kept gardens, the traveller arrives at Parramatta with its quaint old church, its fine domain with sturdy English oaks of magnificent growth, its glimpses of river, its old King's School, and its many evidences of change from the old to the new. From Parramatta (which is but 14 miles from Sydney), to Penrith, there are farms, and dark-leaved orange groves sweet-scented and laden with golden fruit; villages and townships and little homesteads where peace and contentment seem to reign; orchards and cultivated fields with rich brown soil on the hill sides; fine horses, splendid cattle, and cottages with troops of sturdy children. At Penrith, 34 miles from Sydney and 88 feet above sea-level, the country is flat, and the Nepean River which flows in graceful contour is spanned by a magnificent iron bridge supported on four massive piers of solid masonry. The train speeds across the Emu plains which are walled in by the Blue Mountains, so-called on account of the azure haze which covers them as with a bridal veil and is to the everlasting hills what the bloom is to the peach. Scaling the mountain side by a zigzag road, which is one of the "show" works of the colony illustrative of engineering audacity, in the course of a few miles the train climbs to an elevation of 700 feet. At Blaxland's platform, 42 miles from Sydney, the altitude is 766 feet above sea-level.
