turners in the south of Europe ; but it is seldom used here for any purpose but that of 

 whetting the knives of leather-cutters. It is very porous. The ancients supposed 

 that it had the property of separating wine from water by filtration, an error arising 

 from the wood absorbing the colour of the liquid in its passage through the pores. On 

 the Continent at the present time it is sometimes used in thin slices as a filter. The 

 Ivy is sometimes eaten by sheep and horses, but it is not a favourite food. In the 

 " Winter's Tale " we read of the shepherd who found Perdita, being led to the sea-side 

 in the hope of finding two of his sheep which had strayed " browsing on ivy." After all, 

 the charm of the Ivy consists in its unrivalled pertinacity of growth, its rich colour, 

 and its associations with much that is interesting in history. From the days of Pliny 

 it has formed a favourite embellishment of dwelling-houses. In a letter to Apollinaris, 

 the consul, describing his principal seat in Tuscany, represents the trunks of his 

 plum-trees to be entwined with it, and extending so as to connect them together. 

 Hasselquist says, that about Smyrna it forms hedges and ornaments to every garden. 

 These classical associations may add somewhat to the interest with which we regard 

 our old ivy-grown buildings, bxit they cannot add to the delight which every lover of 

 nature must feel in contemplating the picturesque beauty with which it clothes every 

 object to which it attaches itself, be it a rugged cliff, a ruined wall, or the dying trunk 

 of an old tree of the forest.
