important paper on the plants of western Lake Eri^. The groups of water 

 and swamp plants are presented. The usual hydrophytic "adaptations'' are 



■ 



found, and a number of anatomical figures are given. Some excellent plates, 

 showing the life forms of character species, especially Chara, accompany the 

 article. — H. W. Clark (Proc. Ind. Acad. Sci. iqoi : 128-IQ2. 1902) gives 

 a list of plants with ecological notes from Eagle (or Winona) lake, Indiana, 



and vicinity. — Miss Lucy Youse [idem 192-20-I-) discusses the plant ecology 



of Winona lake. She treats the dynamics of the vegetation, sketching the 

 changes from the lake and swamp stages to the forest or prairie, and from 

 the bare morainic hills to the forest of beech and maple. ^W. M. Mills 

 (Chicago: The Quadrangle Press. 1902) has also studied the above lake, 

 mainly from the standpoint of physiography, but adds some ecological notes. 

 — M. T. Cook (Proc. Ind. Acad. Sci. 1901:^66-272. 1902) sketches the 

 development of vegetation in abandoned rock quarries at Greencastle, 

 Indiana. — E.J, Hill(Bu1L Torr. Bot. Clubag : 564-570. 1902) gives some notes 

 on recent adventives in the Chicago flora. — F. E. McDonald (Plant World 

 3: 101-103. 1900) describes a sand dune flora in central Illinois, along the 

 Illinois river. Uunes of pure sand, some a hundred feet high, are formed. 

 Querctis Marylandica is the leading tree. As might be expected, many species 

 are common to the Lake Michigan dunes. — H. C. Cowles' paper on the physio- 

 graphic ecology of Chicago and vicinity appeared in this journal (Box. Gaz, 

 31:73-108, 145-182. 1901). as well as H. N. Whitford's paper (?^^;/z 289- 

 325) on the genetic development of the forests of northern Michigan, and 

 E. J. Hill's paper {idein 29:419-436. 1900) on the flora of the White Lake 

 region, Michigan. — C. A. Davis (Jour. Geol. 9:491-506. 1901) has con- 

 firmed his previous view on the origin of Michigan marl (see Box. Gaz. 

 31:361. 1 901), and adds some new results. — Emma J. Cole's catalogue of 

 the Grand Rapids (Michigan) flora has been noticed (Box. Gaz. 31 : 437. 

 1901); a number of southern trees, such as Asimina, Cercis, Carya, Morus, 

 Nyssa, Gymnocladus, Liriodendron, Cornus florida, probably find here their 

 northern limit.— V. M. Spalding (Science 15:402. 1902) has projected a 

 survey of the Huron valley, Michigan. The influence of artificial changes 

 on certain plastic forms has been very great. — H. S . Reed (Bot. Gaz. 34 : 1 25- 

 139. 1902) has contributed the first paper to the above survey. His topic is 

 the ecology of a glacial lake, and the paper is particularly valuable because of 

 its dynamic treatment and careful quantitative work. — H. C. Cowles' paper 

 dealing with the influence of underlying rock upon the vegetation has been 

 reviewed previously (Box. Gaz. 33:316. 1902)— B. E. Livingsxon (Report 

 Mich. Geol. Surv. 1901 : 79-103. I902) has published on the distribution of the 

 plant societies in Kent co., Michigan. His results will soon be published in 

 this journal, and it may be merely noted here that his physiographic results 

 agree with those of the reviewer. He strongly urges the moisture-retaining 

 power of the soil as the decisive factor in plant distribution. — E. Brunxken's 

 valuable studies in Wisconsin have been noted (Box. Gaz. 34:149. 1902).
