Colney Hatch is not so extensively embarked in industrial and agricultural pursuits as the North and East Riding Asylum, where the patients are received from a mixed manufacturing and agricultural population, and the produce of their fields and workshops is much greater than could be extracted from worn-out metropolitan patients. Not only do the lunatics rear the vegetables, but they take them to the asylum gates and dispose of them to the public. The result affords a proof of what we hold to be a settled principle, that chronic cases of insanity are greatly benefited by as much intercourse as possible with the saner part of the community. In accordance with the opinion that pursuits of lunatics should be similar to their pursuits in former days, the south wing of Haslar Hospital is devoted to the officers, seamen, and marines of her Majesty's fleet who are afflicted with insanity. Every window of the building commands a fine view of Spithead and the Isle of Wight, and here the old Salts can sit and watch the splendid panorama crowded with vessels, and active with that nautical life which recalls so many happy associations to their minds. They form fishing parties, make nets, and go on pleasure excursions in row and sailing craft. The "madman's boat" of eight oars, manned by patients and steered by an attendant, is well known to the sailors on the Solent, and so harmless are they considered, that young ladies often accompany them on trips to the Isle of Wight, implicitly trusting in their seamanship and politeness. Mental labour, as a means of cure, has not been adopted in England to any great extent; most asylums have their libraries, in which attentive readers are always to be found, but the inmates rarely attempt to produce amusement or instruction for their fellows. There is one signal exception to this rule in Murray's Royal Asylum at Perth. This establishment, under the superintendence of Dr. Lauder Lindsay, appears to be the very focus of intellectual activity. The programme for the winter session of 1856-7 reads more like the prospectus of the Athenæum of some large city than the bill of fare for a lunatic asylum. Famous professors reflect in its lecture-room the philosophy and science of the outer world, and their choice of subjects would not be disavowed by the committee of a London Scientific Institution.
