a xylotheque

A xylothek is generally speaking a collection of simple pieces of wood specimens placed together in some kind of cupboard. In a refined form it is in the shape of "books" where you can find details from the tree inside, everything arranged as a "library". This latter form flourished in Germany around 1790-1810. Four different manufacturers existed and three of them offered their products for sale. The Alnarp collection is an example of that.

Each "book" describes a certain tree species and is made out of the actual wood (the "covers"). The spine is covered by the bark, where mosses and lichens from the same tree are arranged. "Books" of shrubs are covered with mosses with split branches on both covers and spines.

Inside there are dried leaves, flowers, fruits, seedlings, a piece of the root, cut branches, seeds - similarly organised in every "book". Inside the spine there is a very nicely written description of the biology of the tree species and also a description of how to use it practically.

Dale Air started life as an air-freshener firm. Then founder Fred Dale, who died earlier this year, found a lucrative sideline.

He was invited to mix familiar odors from the 1920s for use in old peoples' homes. These triggered memories and encouraged conversation among elderly residents.

Dale never looked back.

Soon museums were commissioning smells such as Dead Roman Soldier's Armpit and Viking Loo.
