TIlia, Linn. The etymology of this word is entirely 
unknown ; in Dutch it is called Linden, in Anglo- 
Saxon Lind, and in English Lime-tree. Linn. 13, 
Or. 1, Nat. Or. Tiliacece. Ornamental, lofty-growing 
trees, well suited for avenues and parks. They 
thrive well in any soil, and are increased by layers 
or seeds : if by layers, the tree must be cut down 
close to the ground, and from its roots a great 
number of shoots are produced, in the following 
year ; these will be strong enough to lay down the 
following autumn. Trees raised from seed are far 
preferable to those raised from layers. The Russian 
bass-mats are made from the inner bark of the 
lime-tree ; while the wood, from its being light and 
white, is much used by the carver, and musical 
instrument-maker. Synonymes ; 1 . T. argentea. 2.
