Hicoria Alba and Hicoria Glabra; Carya Blanc and Carya des Pour- 

 ceaux (White hickory and pig hickory). — Trees native to America, 

 relatives of the wahiuts, which have somewhat the same value and re- 

 quirements as the black walnut. 



(Apparently very little hickory has been grown in France, since 

 there is no species having wood which closely resembles it, and its high 

 technical value is probably unrealized. It is doubtful if the hickories 

 ever become popular there. There would be the added difficulty of 

 securing seed from the desirable species since it is doubtful if many 

 French nurserymen are familiar with the specific identity of the large 

 number of American hickories. The difficulty of handling these 

 species in the nursery would likewise have to be reckoned with.) 



Primus Serotina; Cerisier tardif (Late cherry). — An excellent tree, 

 very hardy in our climate. It prefers soils mellow, moist, and deep, 

 with a certain degree of fertility, but it accommodates itself to rela- 

 tively poor sandy soils, and does not seem to dread limestone soils. 

 This species even though its growth is slow is not without interest 

 from a forestry point of view. 



(Boppe and Jolyet in Les Forets state that this species is frequently 

 confused by nurserymen in France with Primus Virginiana, the Amer- 

 ican choke cherry. Since the latter species is perfectly worthless from 

 a forestry viewpoint, the importance of certified seed and stock in 

 connection with this species is evident.) 



Liriodcndron Tidipifera; Tidipier de Virginia (Virgina tulip). — A 

 tree interesting to propagate under the same conditions as the poplars, 

 especially on siliceous soils. 



Betnla Lntea; Boidcau jaune (Yellow birch) and Bctula Lenta; 

 Bouleau merisier (Cherry birch). — Woods much sought after by cab- 

 inet makers. 



In conclusion it seems sufficiently evident that it is important for 

 seed dealers and nurserymen who contemplate shipping seed or nursery 

 stock to France to understand fully the nature of the species required 

 rather than to offer species suitable only for our own conditions. A 

 recent communication of the Director General of the Service des 

 Eaux et Forets to the American Forestry Association emphasizes this. 

 He says, according to the translation of his letter published in the 

 September, 1920, issue of American Forestry: "Seeds of certain 

 species that are little known in France . . . will be given special 

 care and study and will be planted in the nursery of forest school at 

 Barres." (The national arboretum is located there and most of the 

 species mentioned have first been tested at this institution.) 



The high regard with which certain of our western conifers are 

 regarded in France might lead to experiments to shpw their value in 



our own countrv.
