The instruction of garden pupils is specifically indicated as a purpose of the institution, and among the subjects that are mentioned as forming a part of the purpose of its founder are horticulture, arboriculture, medicine and the arts, so far as botany enters into them, and scientific investigations in botany proper, vegetable physiology, the diseases of plants, the forms of vegetable life, and of animal life injurious to 
The Garden Home. vegetation, and experimental investigations in horticulture, arboriculture, etc.; but the testator wisely adds: 'I leave details of instruction to those who may have to administer the establishment, and to shape the. particular course of things to the condition of the times.'
The intention and obvious need of maintaining the establishment as an ornamental garden are evident in the many references to it as a fundamental idea, and Mr. Shaw very specifically states that he considers it 'an important feature to always keep up the ornamental and floricultural character of the garden.' Direction is given that the yearly net revenue from the endowment shall be applied 'first to the payment of the salaries of the director, assistants, professors and gardeners, and the payment of the wages of the employees and laborers, in keeping up the grounds in good style and providing for the preservation and increase of the plants and trees, and preserving the buildings and inclosures of the grounds, and secondly to the purchase of plants, flowers, and trees, additions to the library, the enlargement and improvement of the garden when necessary or advisable, and such other expenditures as from time to time may lie found necessary' in furtherance of the purposes of the testator.
