Turner's Herbal, in IjjI : it is mentioned by all subsequent British authors as 

 of doubtful indii^enousness. From the facility with which it is propagated, the 

 hardiness and vigorous growth of the tree, its various uses, especially, as Dr. 

 Walker observes, for forming domestic utensils, and also the beauty of its buds 

 in spring, and of its foliage in early summer, it has been very generally 

 planted. 



Properties and Uses. The wood, when the tree is young, is white ; but, as it 

 gets older, the wood becomes a little yellow, and often brown, especially 

 towards the heart. It is compact and firm, without being very hard ; of a fine 

 grain, sometimes veined, susceptible of a high polish, and easily worked, either 

 on the bench, or in the turning-lathe. It does not warp, and is not likely to 

 be attacked by worms. It weighs per cubic foot, newly cut, G4 lb. ; half dry, 

 5Glb. ; dry, 48 lb. It loses, in drying, about a twelfth part of its bulk. 



In France and Germany, it is much sought after by wheelwrights, cabinet- 

 makers, turners, sculptors in wood, manufacturers of musical instruments, and 

 especially of violins, and makers of toys and other small wares. The roots, 

 which are often agreeably veined, and the stools or stumps where the plant 

 has been long treated as a bush, and cut periodically for cop[)ice-wood, is 

 eagerly sought after for curious cabinet-vvorks and for inlaying. The wood is 

 used for pestles, for tables,rollers, spoons, plates, and other household articles ; 

 it is also used for gun-stocks, and in every kind of structure, whether under 

 water or in the air. According to JNI. Hartig, the principal German writer on 

 timber trees and their uses, the wood of the conmion sycamore is the most 

 valuable of all woods as fuel, both for the quantity of heat which it gives out, 

 and the time that it continues burning : it surpasses the beech, in these respects, 

 in the proportion of 1757 to lo40. Converted into charcoal, it is superior to 

 the beech in the proportion of 1G4-7 to 1600. The leaves, gathered green and 

 dried, form an excellent forage for sheep during the winter. The sap has 

 been drawn from the trees in Germany, and various experiments made with it. 

 At first, it is as clear as water, and sweet ; but, after it has run from the tree 

 for some time, and begins to run slowly, it takes a whitish colour, and becomes 

 sweeter and of a thicker consistence ; though this thick sap is found to contain 

 less sugar than that which comes of}' first, and is quite clear. From a tree 18 in. 

 in diameter, from which the sap was allowed to flow for five days, 36 quarts 

 were obtained. The proportion of sugar produced by the sap varies. Sotne- 

 times an ounce of sugar from a quart of liquor has been obtained ; but, gCTierall)', 

 not so nmch. The variations depend on the age of the tree, the vigour of its 

 growth, the nature of the soil, the temperature of the season, and a number of 

 other circumstances of which little is known. In Scotland, Sir Thomas Dick 

 Lauder informs us, incisions were made in the trunk of a sycamore tree of 

 45 years' growth, at 5 ft. from the ground, in the beginning of March, 1816. 

 " A colourless and transparent sap flowed freely, so as in two or three hours 

 to fill a bottle capable of containing 1 lb. of water. Three bottles and a half 

 were collected, weighing, in all, 3 lb. 4 oz. The sap was evaporated by the 

 heat of a fire, and gave 214 grains of a product in colour resembling raw sugar, 

 and sweet in taste,"with a peculiar flavour. After being kept fifteen months, 

 this sugar was slightly moist on the surface. The quantity of sap employed in 

 the evaporation was 24,960 grains, from which 214 grains of sugar were ob- 

 tained : therefore, 1 16 parts of sap yielded one part of sugar. The experiment 

 was made at Cannon Park, in Stirlingshire, on the 7th and 8th of March, 1816. 

 {Lauder's Gilpin, i. p. 124.) Dr. Walker states that the sap is made into wine 

 in the Western Highlands of Scotland. 



In Britain, the uses to which the A. Pseudo-T'latanus is applied are much 

 less various than in France and Germany. The species is a very umbrageous 

 one, from its numerous branches, and numerous and large leaves; and hence it 

 is eligible in all cases where trees are wanted to afford dense shade : it may be 

 on this account that it is sometimes seen bounding the homesteads of a farm, 

 and on the sunny side of the dairy in the farm-yard. It is used in joinery 

 and turnery, and cabinet-making ; by musical instrument makers ; for cider-
