 Academy of Sciences, Arts and Letters, vol. XV (1904), 1905,

 being as follows : R. adusta, alutacea, amoena, atropurpurea, 

 decolorans, delica, emetica, foetens, furcata, integra, lactea, lutea, 

 ochrophylla, var. albipes, ochracea, olivascens, pectinata, roseipes,

Some of the earlier observations bearing on the question as 

 to the manner in which Rusts pass the winter are given, then 

 experiments detailed by the author of "Observation on the Winter- 

 ing of Grain Rusts," are published in the Transactions of the 

 Wisconsin Academy of Sciences, Arts and Letters, Vol. XV 

 (1904), 1905. The work pertained to the winter of 1902-3. The 

 conclusion reached was, that in the latitude of Madison, in a 

 period of three months, during which the temperature scarcely 

 raises above the freezing point, viable uredospores may be obtained 

 at practically any time. The spores taken from very exposed sit- 

 uations gave about 10% of germinations. Of Oat Rust spores 

 collected late in January, 60% germinated.

Fink, Bruce. 



Professor Bruce Fink gives in The Plant World for No- 

 vember, 1906, some account of "Lichens : their Economic Role ;" 

 discussing briefly the symbiotic relationship and mode of life of 

 these plants, then outlining their use as soil-makers by attacking 

 rocks, dealing with the uses of Lichens as food — the Cladonias 

 for moose, caribou, and deer, the Cladonia rangiferina for the 

 reindeer; for man the Lecanora esculenta (Northern Africa), 

 Cetraria islandica (Iceland), also dyes of various colors have been 

 extracted from Lichens and are still being used in various ways. 

 These colors are usually reds, purples or blues, and they are used 

 for coloring cloth, wood, jiaper, etc.
