Director, had up to this time been housed in his private residence. Now they found more convenient accommodation, where they would be more accessible for reference, in a building belonging to the establishment. In 1857 the Museum No. I. was opened. For long the collections had exceeded the space in the older Economic Museum (No. II.). This was, however, retained for the specimens belonging to the Monocotyledons and Cryptogams, while those of the Dicotyledons were arranged in the new and spacious building of No. I. In 1861 a reading-room and lecture-room for gardeners was opened, and in 1862 the central portion of the great range of the Temperate House was completed from plans approved in 1859. The wings which now complete the original design were added many years afterwards. In 1863 the old Orangery was disused as a plant-house, and diverted to the purpose of a Museum for Timbers, chiefly of colonial origin. It is now known as Museum No. III. The above may serve as a summary of the more important material additions to the Kew establishment, made during the life of Sir William Hooker. It will be clear that his activity must have been unceasing, in working towards the ideal sketched in the report of Dr Lindley. His efforts never abated till his death in 1865, in the 81st year of his age. The establishment of Kew has developed further as years went on. But as he left it, the essentials were already present which should constitute a great Imperial Garden. Truly Sir William Hooker may be said to have been the maker of Kew, if regard be taken merely of the material establishment. In no less degree may he be held to have been the maker of Kew in respect of its scientific collections, its methods, and its achievements. To these his own untiring activity contributed the driving force, while his wide knowledge, and ready apprehension of fact gave the broad foundation necessary for successful action. But as the period of development of Kew in these respects was but the culmination of the work already initiated in Glasgow, it will be well to review Sir William Hooker's scientific achievements over the whole of his professional career, including the Glasgow period together with his later years at Kew.
