FORESTRY. 957 



arc given. A mimhri- of the more iniportaiit forest districts are 

 described in some detail. The prevailinjy species in these forests are 

 spruce, followed by beech and fir. The Crottendorf range, which is 

 said to be remurka])le for the large proiitit yields, is described at con- 

 siderable length. The net revenue from these forests for the past 10 

 years has been liJl.9 marks per hectare, which represents 4.35 percent 

 of the estimated value of the range. In some of the forests consider- 

 able damage has been done to 3"ouug spruce trees b}^ the fungus Tra- 

 metes radiciperda. 



Forests in the G-rand Duchy of Baden {/adkm J^^^m's-ter, 26 

 (J 900), y^tK 9, (I pp. pp. l,i'~>^ji<jx. I'i). — The forests of the Grand Duchy 

 of Baden are said to occupy a total of 36.2 per cent, as compared with 

 an average of 26 for the whole of Germany. This area is divided into 

 State forests, 95,000 hectares; forests belonging to towns, villages, and 

 other public corporations, 270,000 hectares; and private forests, 

 180,000 hectares. Of these forests, the beech occupies 26.4 per cent 

 of the total forest area; oak 11.1 per cent; other broad-leaved species 

 14.1 per cent; while spruce occupies 20.8 per cent; silver fir and 

 Scotch pine each 13.6 per cent; and other conifers 0.4 per cent. The 

 methods of treatment followed within the Grand Duchy are described 

 and grouped under the heading of high forest and coppice. The 

 methods of administration are described and working plans for a 

 mmiber of State forests are given. The method pursued in charcoal 

 burning is described at considerable length. 



The protection of shade trees in towns and cities {Connecticut Slate Sta. BxiL 

 ISl, }>p. .iO, plx. 9). — This l)ulletiii i.s the report of a committee appointed by the 

 mayor of the City of New Haven, Conn., to investigate the subject of the protection 

 of shade trees. The present condition of the street trees was indicated and various 

 causes of the destruction of trees were mentioned. iSuggestions are given for protect- 

 ing shade trees against these injuries, and the duties of the city forester are outlined. 

 The necessity for a nursery to provide shade trees for those which have been 

 destroyed from various causes is shown, and descriptions given of the varieties of 

 trees most suitable for street planting. 



Concerning- a severe injury to street trees through the escaping- of illu- 

 minating gas, C. Wejimek {Ztschr. Pflanzenkranl:, 10 {1900), No. 5, pp. 267-369, 

 ]>l. 1). — An account is given of the severe injury to a number of trees of Ubnu.'i cam- 

 pestris. The injury was caused by a break in a gas main, and it was comnuinicated 

 to the trees through their roots. The bark fell off, the trunks of the trees showing 

 the injury early in the spring, while the buds and twigs appeared in normal 

 condition. 



Some unrecognized forms of native trees, 8. Coulter {Proc. Indiana Acad. 

 Sci. 1899, pp. 113-116). — Brief descriptions are given of a number of well-marked 

 forms of native trees which the author thinks possiblj^ worthy of varietal rank. 

 Among those described are two forms of the papaw which are said to be easily dis- 

 tinguishable. One has a large fruit, which becomes a rich yellow upon ripening; 

 the other has a small fruit, becoming white when ripe. The leaf characters are also 

 different. Three easily distinguishable forms of black walnut are also described, 

 and forms of the common tulip tree and persimmon are also said to exist, in which , 

 marked characters may be noted.
