The following passages are quoted from the Englishtranslation of this report, and will serve to show, better than anylong discussion, the present situation of the timber-impregnationquestion in Europe. Under the heading of Wood for all structuralpurposes we read, page 8: As far as the substances which are usedby the different managements to prevent decay and to produce non-inflammability are concerned, we have to report that the majority ofthe managements do not pay much attention to this subject. Page11: The data we have received on the properties of pickled andunpickled wood are not veiy comparable, as the respective conditionsare very different. Conclusions: 1.
