they may roam for purposes of study. The line of march then 

 is usually confined to the country roads, choosing the byways 

 more than the highways. The party tramps along, looking here 

 and there for interesting plants in bloom, when suddenly a 

 whistle is blown which is the signal for a halt. The professor 

 is seen standing a little in advance of the party, holding up a 

 plant for general inspection. The students cluster around and 

 the professor asks questions. First, what is the plant; second, 

 where does it belong, what are its peculiarities of structure, 

 what are its uses, adaptations, etc. Sometimes the answers 

 come in chorus, and again there is silence or a solo! Usually at 

 the close of the study of the individual plant some additional 

 remarks are offered by the professor and the march is then 

 resumed. These stops occur at frequent intervals. At each time 

 students are expected to note the names of plants discovered 

 and suppleinent the information given by other informati(m to 

 be secured from the manuals. Frequently plants are brought in 

 from the side lines by students themselves. 



The situation of Freibourg, lying as it does near the Rhine 

 Valley on the one hand and at the gateway of the most attractive 

 and interesting part of the Black Forest Mountains on the other, 

 makes it possible to vary the character of the flora to be studied 

 from day to day by simply changing the route. Thus the 

 mountain flora may be studied on one excursion and the low- 

 land area with a different flora explored the next time, or it is 

 even possible in an extended walk to include both upland and 

 lowland. 



Germans, like Englishmen, are good walkers. The "week 

 end" tramps with rucksack on back are very much in vogue in 

 Germany, and the mountain paths in this particular region are 

 freely patronized during the summer by cheerful pedestrians. 

 This kind of exercise makes for the development of an essential 

 quality in a naturalist, namely the ability to walk. In these 

 field excursions I discovered that the leader usually set a lively 

 pace. One of the last excursions I had the privilege of attending 

 occurred on the 12th of July, 1908, and I found on returning 

 home and comparing the route with the map that we covered 

 about ten miles in a little over three hours. I found also the 

 following list of plants were collected and many of them dis- 

 cussed. The list is uninteresting in itself, but simply shows the 

 flowering plants which happened to attract our attention in this 

 short ramble among the hills of the Schwarzwald in the first half 

 of July.
