THE Missouri Botanical Garden has recently celebrated the twenty-fifth anniversary of its foundation and the New York Botanical Garden its twentieth anniversary. Within these short periods these gardens have taken rank among the leading scientific institutions of the world. Botanical gardens were among the first institutions to be established for scientific research; indeed Parkinson, the "botanist royal" of England, on the title page of his book of 1629, which we here reproduce, depicts the Garden of Eden as the first botanical garden and one which apparently engaged in scientific expeditions, for it includes plants which must have been collected in America. However this may be, publicly supported gardens for the cultivation of plants of economic and esthetic value existed in Egypt, Assyria, China and Mexico and beginning in the medieval period had a large development in Europe there being at the beginning of the seventeenth century botanical gardens devoted to research in Bologna, Montpellier, Leyden, Paris, Upsala and elsewhere. An interesting survey of the history of botanical gardens is given in a paper by Dr. A W. Hill assistant director of the Kew Gardens, prepared for the celebration of the Missouri Garden, from which we have taken the illustration from Parkinson and the pictures of Padua and Kew. The papers presented at the celebration have been published in a handsome volume. It includes addresses by a number of distinguished botanists, though owing to the war several of the foreign botanists were unable to be present. Dr. George T. Moore, director of the garden, made in his address of welcome a brief statement in regard to its origin in the private garden and by the later endowment of Mr. Henry Shaw. Mr. Shaw came to this country from England in 1818, and with a small stock of hardware began business in one room which also served as bedroom and kitchen. Within twenty years he had acquired a fortune and retired from active business to devote the remaining forty-nine years of his life to travel and to the management of a garden surrounding his country-home on the outskirts of St. Louis. In 1859 he erected a small museum and library, and in 1866 Mr. James Gurney was brought to this country as head gardener. Mr. Shaw died in 1889, leaving his estate largely for the establishment of the Missouri Botanical Garden, but providing also for the Henry Shaw School of Botany of Washington University and a park for the city. With this liberal endowment constantly increasing as the real estate becomes more productive, Dr. William Trelease, the first director, and Dr. George T. Moore, the present director, have conducted an institution not only of value to the city of St. Louis but largely contributing to the advance of botanical science.
