For cultivation in the north you will be interested in J. Manshurica originating in the Far East and very hardy. It is cultivated and produces fruit in Leningrad, young specimens of it were planted on the Solovetsky Islands in the White Sea and there outlived excellently. Concerning the list of trees appended to your letter, I can give you the following information. _J. Regia_ grows well in the park of Botanic Institute in Leningrad, attaining 8-10 M.; in the southern part of Smolensk district the tree produces fruit as far as Minsk. There is a considerable number of fruit producing specimens in the Masir district in the north of White Russia. _J. Sieboldiana_ freezes up in cold winters in Leningrad. _J. cinerea_ is very hardy and effects self-polinasation in White Russia; near Kasan there is one specimen producing about 100 fruits yearly. _J. rigra_ produces fruits in Koslon. _Corylus Colurna_--a large old specimen esctant in Leningrad rather frequently observed in many parks of European U. S. S. R. _C. Acellana_ is widely spread in a wild state attaining Ladoga-laxe. _C. Mascima_ frequently in the Crimea and the Caucasus. _Castanea Sabiva_ grows in the Caucasus only, and cultivated in Urraina. Castanea Henryii Corylus chinensis. C. Lacquement and Cticstica I do not know in U. S. S. R. _C. Seguinu, C. Crensta_ and _C. Mollissima, separate_ strains probably to be had in Suchum. From Divisional Forest Officer _Utilization Division, Baramulla Kashmir_ There are two distinct species of of walnut growing here. One which grows from 3,500 to 7,000 feet above sea level near about habitations and on rich fertile soil has got good big sized nuts which are very easy to break even with the pressure of hand, and about which you probably seem interested. The other species grows higher in the forest up to about 11,000 feet elevation. It has hard nuts which cannot be broken easily and have moreover very little kernel as compared to former species. Even the timber of both the species is distinctly different, in as much as the former has dark gray color and the latter has reddish gray. Regarding nomenclature the botanists differ. The former species is named Juglans regia hin. The latter species which is wild may be called Juglans fallax, Dode or Juglans Kamaonia, Dode, but actually it is a bit different from either and is something midway between the two and so is yet to be determined properly. Corylus colurna is the only species of Corylus found here out of your list. B. The altitudes of walnut zone has been stated above. Corylus Colurna also grows between 8,000 and 11,000 feet. Both the walnut species are confined to Kashmir and Chamba states, while Corylus Colurna grows all over the Himalayas.
