recounted his time visiting with Spegazzini, who was then 66 years old:

Dr Spegazzini is an old man, but strong in body, young in thought, and still full of the spirit of adventure. He has just returned from Tierra del Fuego, is planning to go to Europe next year, and promises me to come to the United States the following year 'if nothing happens'. He was born in a village in Italy and was a student of the fungi there before coming to Argentina. He has described a great many South American plants in various groups but his work is poorly known elsewhere and few of his specimens have been seen by other botanists. ... The Doctor is exceedingly genial in manner and very kind hearted. He and his son stayed with me all day long, showing me specimens, photographs and publications; giving me anything I wanted for our herbarium; taking me out to a sportsman's club for lunch; visiting the museum; and going on a short collecting trip in the woods. We talked French, German, English, Latin and Spanish indiscriminately and recklessly, keeping up a continuous flow of conversation lest our ignorance in certain languages be discovered.
