NOTES AND COMMENT 47 



day was initiated by rising at 5 o'clock and starting off by train for the 

 Norfolk Broads, where three delightful days were spend under the guid- 

 ance of Miss Pallis in studying the rich aquatic, marsh, and fen flora of 

 that region. These days alone sufficed to show that the British Isles, 

 in spite of their great density of population, have large areas of natural 

 vegetation admirably adapted for intensive study. 



A day was spent at Blakeney, Norfolk, under the masterly leadership 

 of Professor Oliver. We studied there the intensely interesting salt 

 marshes and gravel dunes which have proven so rich in problems that 

 Professor Oliver has established at this point at seaside laboratory for 

 their study. Three days were spent about Manchester, one in the fam- 

 ous Derbyshire dales, where Dr. Moss enthusiastically demonstrated 

 retrogressive succession in the limestone forests. Two days were spent 

 under the leadership of Professor Weiss and Dr. Woodhead on the 

 mountain moors, which exhibited, at least to the American guests, an 

 entirely new type of vegetation, not alone in its composition, but also 

 in the astonishing evidences of retrogression. This part of the trip will 

 be remembered also for two delightful dinners, one at Manchester, where 

 the hosts were Professor and Mrs. Weiss and Dr. Lang, the other at 

 Huddersfield, where the Cave Club acted as our host. Space forbids 

 even the mention of most of the numerous kind friends who served as 

 hosts at luncheons and teas during the progress of the excursion. 



The dunes at Southport, to which a day was devoted under the 

 guidance of Professor Weiss, proved to be of great interest. In north- 

 western England the leaders were Dr. Rankin and Dr. Lewis, and there 

 we became well acquainted with lowland moors (cross sections being- 

 found to aid in elucidating their problems) and also with the mountain 

 moorland of Cross Fell. 



The several days devoted to Scotland were packed full of interest. 

 In the Scottish field trips our efficient guide was Dr. Smith, assisted 

 by Dr. Crompton, who interpreted the geology and physiography. 

 At Edinburgh we explored the Botanical Garden and were most roy- 

 ally entertained at dinner by Professor and Mrs. Balfour. The forests 

 of Dunkeld, the interesting and floristically rich alpine vegetation of 

 Ben Lawers (where Professor Balfour was the leader), and the lovely 

 scenery of the Trossachs appealed equally to the scientific and to the 

 esthetic sense. The sojourn in Scotland was fittingly terminated by 

 a luncheon with Professor Bower and Dr. Lawson at Glasgow. 



Nearly a week was spent in Ireland and this time was all too short. 

 Our guide here was Mr. Lloyd Praeger, ably assisted by his wife. One
