220 justification of their acquisition, it is not at all improbable that the passage of time will see their utilization to an even greater extent by investigators not connected with the administration of the establishment. Whatever it possesses is freely placed at the disposal of any one capable of making good use of books or material, and while its own staff, however developed, will always comprise but a small part of the persons capable of making good scientific use of its treasures, it is probable that a recognition will grow with the years, through at least the entire central part of our country, that a visit to the garden is not only possible and practicable, but almost a necessity for all of the botanists outside of the few large universities, who desire to do in its best form the work that lies in the line of their interest and training. Much use has already been made of the garden by men who would not have done their work so well without this help, and much more use of it would doubtless be made were it not for the fact that travel and residence in a city are found more expensive than staying at home, when the isolated worker counts up the cost and consults his limited income. It may be remarked, however, that the man who counts cost too closely through life is often the man who sacrifices future usefulness to present economy, and it may safely be said that few lines of saving are less profitable in the long run than those pursued at the expense of the equipment and wide acquaintance on which professional and financial success usually rests.

Prophecies are always of uncertain value and attended with danger if the prophet seeks a reputation in that field: I shall hardly venture, therefore, to say much about the detailed future of the garden. This much, however, may be said with certainty, that its endowment appears to be so ample and so well founded that, though growth and attainment will be gradual and large immediate undertakings are not within its power, its perpetuity as an important and growing center of study and education are beyond question. The research work already in progress in the garden under the control of the government is suggestive of the continued attainment of better, and larger results through cooperation with other establishments than would be possible to either alone. That the grounds will be greatly enlarged, that a supplementary garden of much larger size and more picturesque conformation will some day be opened at a distance from the smoke of the city, which has already sounded the death knell of some of the plants that were formerly cultivated with success in the present garden—which, under the provisions of Mr. Shaw's will is certain to be maintained as the real center and home of the establishment whatever adjuncts it may have—and that there will be erected in the near future a system of large conservatories of modern construction, worthy
