426 First European Journey 



versity of Chicago, wrote Smith in February he was " grateful " 

 that once again he was interesting himself in the Laboratory and 

 that the Department of Agriculture would probably again take a 

 room for research during the approaching summer. Soon after 

 Smith had been elected a trustee of the Laboratory, the corpora- 

 tion had undergone a crisis in its affairs but had emerged stronger 

 than ever with its traditional policies intact." During 1903, 1904, 

 and 1905, the corporation of the Marine Biological Laboratory 

 had been enjoying an annual grant from the Carnegie Institution 

 of $10,000 for the privilege of using twenty tables at the Labora- 

 tory. In 1906, however, this annual grant had not been available 

 by reason of the Carnegie Institution's plans to establish its own 

 department of marine biology, which became located at Tortugas, 

 Florida. Smith, therefore, in 1907 arranged, as he did at least 

 once before, for the Department of Agriculture to have a room 

 at the Laboratory and probably with a view to pursuing some of 

 his own researches there that summer. For, on August 11, 1907, 

 in one of a series of letters which told of his plans and activities 

 and which were written at Woods Hole, he said: " I brought 

 many notes and manuscripts relating to scientific things, for I hope 

 to finish, or nearly finish, the second volume of my book while 

 here this summer and autumn," ^^ Bacteria in Relation to Plant 

 Diseases. 



Other laboratory facilities away from Washington and devoted 

 to plant science investigation were offered him that year. March 

 17, 1907, Hermann von Schrenk at St. Louis had invited Smith 

 to be a visiting scientist at the laboratory there. Von Schrenk, in 

 the sixteenth Annual Report of the Missouri Botanical Garden,^^ 

 had published in 1905 on " Intumescences formed as a result of 

 chemical stimulation," a research some of the experiments of 

 which Smith later repeated to study the effect of ammonia, in 

 addition to various copper fungicides, as causes of intumescences 

 in some plants.*"
