The garden is surrounded by a strong iron fence. Admission 

 is free on certain days of the week, while on others it is to be ob- 

 tained only by the purchase of one of the guidebooks on sale at 

 the entrances. Dr. Engler, the director, and Dr. Urban, the as- 

 sistant director, have beautiful villas near the west entrance, where 

 the large museum building is situated. It is expected that the 

 museum will be completed and the collections moved into it 

 from their present crowded quarters in the old garden within the 

 nextyear. 



The trees of the Tiergarten, a large and beautiful park in Ber- 

 lin corresponding to our Central Park, have been much improved 

 during the last few years by careful attention to conditions of 

 soil, moisture, light, etc. Unter den. Linden, however, the center 

 of the city's life and activity, remains decidedly unattractive in 

 comparison with the beautiful avenues of many other cities, 

 solely because of the motley arrangement and poor condition of 

 its shade trees. It would be far better to cut them all down, 

 renew the soil, and plant several rows of three or four of the best 

 species, changing from one species to another at certain important 



I next made a rather hurried trip to Sweden and Denmark, 

 stopping at Upsala, Stockholm and Copenhagen. Leaving Ber- 

 lin early in the morning and traveling all night, I reached Upsala 

 about noon the next day. In the absence of Professor Kjellman, 

 Dr. Svedelius extended to me the freedom of the museum and 

 allowed me to lack for nothing that could be of service in my 

 work. The mycological collection at Upsala is of the greatest 

 importance, since it contains and is based upon the herbarium of 

 Elias Fries, the father of modern mycology. In addition to the 

 specimens on sheets, there is a fine collection of fungi in bottles, 

 arranged in cases with a black background. This method not 

 only exhibits the specimens to advantage, but entirely eliminates 

 the question of preserving them against insect attack. The 

 present botanical garden contains many of the plants removed 

 by Linnaeus from the old botanical garden, situated on the low- 

 lands along the river, to his country home at Hammarby, and 

 brought back to Upsala after the death of his son. The herbar-
