FORESTRY. 



The cultivated poplars, L. H. Bailey [Neio Yorh Cornell Sta. Bui. 

 <>"^, pp. :J'>'>-:Jo>', Jiiis. ls\. — This bulletir contaius j>eneral remarks upou 

 l)0])lais as applied to hnidscape gardeiiiiig and illustrated descriptions 

 of 12 spec'ies of cultivated poplars. 



It is recommended that poplars be employed only as secondary trees 

 in landscape gardening, and that they should be sparingly planted in 

 situations caretully (diosen for their artistic effect. The Lombardy and 

 silver-leaved or white poplars arc i)referred less than species with 

 heavy, dark foliage and strong growth. For ornamental planting cot- 

 tonwoods and aspens are suggested, and for shelter belts and timber, 

 Certiuensis x)oplar, cottonwood, and balm of Gilead. 



The following species and varieties are described: Yellow xioplar 

 {Populus ((Hfjustifolia), balsam ])()plar or tacmabac (P. hahamifera, 

 Yavs. infermedia, vhninaUs, iiud lutlfolin)., balm of Gilead {P. candicans)^ 

 P. simonil. Oertineusis poplar (P. hiiiyij'olia), cottonwood (P. tuonilifera), 

 black poplar or Lombardy poplar {P. nigr<(, vars. slegans and itfdica), 

 European aspen {P. tyemula)., hirge -toothed aspen {P. fjyandidenUda), 

 common aspen or popple (P. treinuloides), P. sieboldi^ and white poplar 

 (P. alba, vars. cancsccn!^, nirea, and hoUeana). 



Uses of the eucalyptus tree ( V. tS. Consular Bpt. 1894^ Sept.., pp. 

 l-:^o). — Reports from consular otticers at Bordeaux, Marseilles, i^ice, 

 Florence, Home, Lisbon, Barcelona, Calcutta, Havana, and Zanzibar in 

 regard to the limit of cold endurance of tlie eucalyptus, and the hygienic 

 effect of eucalyptus plantations, especially in regard to malaria The 

 lowest temperature given at which any species escapes injury is 17.6^ F., 

 and many si)ecies can not endure a freezing temperature. The opin- 

 ions vary as to the value of the tree in preventing malaria, but it seems 

 to be established that its power in this respect has been overestimated, 

 and that though the miasma may be somewhat abated, the effect is 

 probably due rather to the abundant roots drying the soil than to any 

 exhalations from the tree. The economic value in furnishing timber, 

 gums, perfumers' essences, antiseptic and essential oils, and material 

 for manufacturing packing and blotting paper is touclied upou.
