156 TRANSACTIONS OF ROYAL SCOTTISH ARBORICULTURAL SOCIETY. 
following trees were dealt with:—Pinus rigida*, P. ponderosa, 
P. Jeffreyi, P. laricio, Pseudotsuga Douglasii*, Abies Nordmanniana*, 
Picea sitchensis*, Cupressus Lawsoniana*, Thuja Menziesir, Juniperus 
virginiana, Carya alba*, C. amara*, C. tomentosa, C. porcina, 
Juglans nigra*, Acer californicum, A. sacharinum*, A. dasycarpum, 
Fraxinus pubescens, Betula lenta*, Quercus rubra. Thuja Menzesir 
would succeed very well but for the attack of a fungus (Pestalozzia 
Ffunerea) which has brought all the plantations of this tree into a 
very critical condition. Since 1890 the following additional trees 
have been planted:—Prunus_ serotina, Fraxinus alba, Pinus 
Banksiana, Picea pungens, Abies concolor, Larix leptolepsis, Chame- 
cyparis pisifera, and C. obtusa. 
Up to the present about 1730 acres of State Forest have been 
planted with exotics, which are under the control of the Central 
Investigation Station of Eberswalde. This is over and above 
numerous areas that have been stocked by means of seed got in 
other ways, so that practically no State Forests now exist in 
Prussia that do not contain a greater or less number of exotic 
trees. In the neighbourhood of Eberswalde exotics have been 
extensively tried, where it has been found that they thrive well in 
the cleared patches that are made in woods worked on the uneven- 
aged selection system. 
In preparing the above account of the Sylviculture and Arbori- 
culture of the districts visited by the Royal Scottish Arboricultural 
Society on its Excursion of 1895, I have, on behalf of the Society, 
to express my warmest thanks for assistance rendered by Herr 
Landesforstrath Quaet-Faslem of Hanover, Herr Forstmeister 
Hesse of the Saupark, Springe, Herr Regierungs- and Forstrath 
Betzhold of Hildesheim, Professor Schwappach of Eberswalde, 
and Messrs Heins of Halstenbeck. The Society is specially 
indebted to Professor Schwappach, who not only supplied the 
whole of the matter for Eberswalde and its neighbourhood, but 
who also secured the assistance of the other gentlemen named 
above. As all the above information dealing with State Forestry 
was derived from official sources, and is therefore thoroughly 
reliable, it constitutes evidence of the very greatest value in 
regard to the management and returns of Prussian forests. 
For kind assistance with the translation, I have also to thank 
Professor I. Bayley Balfour and Dr Smith of the Royal Botanic 
Garden, Edinburgh, Mr A. C. Forbes, Bowood, Calne, and Mr 
Robert Ferrier of the Durham College of Science. Wi... Be
