Wcstcrdijk to licr home and laboratory. The Willie Commclin 

 Scholtcn Laboratory, formerly at Amsterdam, had recently ac- 

 quired an estate, and Miss Westerdijk divided her work in plant 

 patholoi^y thus, her research at Baarn and her teaching at Utrecht. 

 Dr. Smith, revelled in the glorious gardens, good greenhouse 

 facilities, and the laboratories where plant diseases were studied. 

 By frequent transfers 16*^0 kinds of fungi were kept alive. He 

 saw many interesting plants, the good library of books on science 

 and literature; and in the evening Miss Westerdijk invited eight 

 of her assistants and special students to meet her American guests. 

 Dr. Quanjer was away from Wageningcn that week. When 

 reached, he pr5mised to be at Utrecht the next day. Miss Wil- 

 brink, discoverer of the hot water treatment against Sereh disease 

 of' sugar cane, had recently returned from Java and Smith, 

 " pleased .with her." ^-'' learned of her efforts "to infect sound 

 cane ... to find the parasite." 



At four o'clock the next afternoon, Dr. Smith addressed fifty 

 students in the University of Utrecht botanical laboratory " on 

 crowngall and its relation to other galls and tumors. [H]e used 

 English, and strange to tell," he said,^-' " all understood me. 

 Students here are taught to use three languages. All can use at 

 will English or German and some also know French. They 

 seemed very much interested and at the close gave me three 

 tremendous rounds of applause." 



Professor Quanjer and two other scientists from Wageningen 

 w^ere in the audience. Smith enjoyed talking with them, and with 

 a professor of plant physiology from the Imperial University at 

 Sendai, Japan, who also heard the lecture. Dr. Went took them 

 around the " new and commodious laboratory," and invited Dr. 

 Smith to attend with him a meeting of the Dutch Academy of 

 Science. He did not accept this invitation, however, since on that 

 day at Amsterdam he planned to re-study "Dr. Deelman's slides 

 of early stages of tar cancer in the skin of mice." 



Dr. and Mrs. Smith returned to Amsterdam and he became more 

 convinced than ever that Deelman was " right beyond doubt. The 

 precancerous stage," he wrote in his journal, ^-^ " is cell-hypertro- 

 phy followed by cancerous invasion. The hypertrophy gradually
