which grow here in profusion and from the autumn coloring of the 
foliage. Probably there is no place in the world where such a variety 
of autumn foHage can be seen in a small area, and the autumn foliage 
season is prolonged here by the large number of Chinese and Japanese 
plants which as a general rule assume autumn colors three or four 
weeks later than the allied American trees and shrubs. As a rule 
Europeans who know the Arboretum are more interested in it in the 
autumn than they are in the spring, for they are not able to see in 
Europe such an abundance of brilliant fruits or such masses of autumn 
foliage. 
Prof. E. H. Wilson, assistant director of the Arnold Arboretum Mr. E. H. 
left Boston for his two years' trip around the world. It seemed highly Wilson's ? '^ 
desirable to Prof. C. S. Sargent to have closer connection made with Trip Around 
the leading horticultural and botanic institutions of the world, and the World 
no man is better fitted to carry out such a project than Mr. Wilson. 
Preliminary to his trip to distant countries, Mr. Wilson will spend six 
weeks in England, where he has not visited for nine years. He expects 
to spend considerable time at Kew Gardens. 
He will then go to Australia, making side trips from there to 
Tasmania and New Zealand. About next May, if his plans work out, 
he will be on his way to India, where he will probably spend several 
months. 
It is expected that Prof. Wilson will accumulate a great number of 
rare and valuable horticultural pubHcations for the Ubrary at the 
Arboretum, as well as many herbarium specimens which will be of no 
little value to students. 
While this is not primarily a plant hunting expedition, undoubtedly ' 
new plants of value will be found, although they are not likely to 
prove hardy in New England. As a matter of fact, the Arboretum has 
been instrumental in introducing many plants which, while not 
adapted to northern climates, have added much to the flora of Cali- 
fornia and Southern states. 
Prof. Wilson is especially interested in securing conifers for 
America, as very few examples of these plants from the Southern 
hemisphere have been grown here. It is felt by the Arboretum au- 
thorities, however, that this work will be greatly handicapped because 
of the drastic rulings of the Federal Horticultural Board, which make 
it necessary that even seeds shaU be sent to Washington before the 
Arboretum is allowed to have them, and the baking process which they 
go through at the capital is often fatal to their germination. 
Members of Garden Clubs, except those living within fifty miles of 
Boston, wishing to visit the Arnold Arboretum, can obtain authority to
