brilliant clay, the eap flows nl)unilantly ; and two or threo gallons of sap 

 are soinetiiiies yieliletl by a single tree in twenty-lour bonrs. Tbe yearly 

 product varies from 2 lb. to 4 lb. of sugar each tree. Trees w Inch grow in 

 low and moist places aflbrd a greater quantity of sap than those which oc- 

 cupy rising grounds; but it is less rich in the saccharine principle. That of 

 iusulateil trees, left standing in the middle of fields, or by the side of fences, 

 is the best. It is also remarked, that, in districts which have been cleared 

 of other trees, and even of the less vigorous sugar maples, the product of the 

 remainder is |)roportionably greater. 



Wild and domestic animals are inordinately fond of maple juice, and break 

 through their enclosures to sate themselves with it. (Mic/iaii.r, p.2li(i.) 

 In Europe, it is not likely that the extraction of sugar from any species of 

 maple will ever be tried otherwise than as a matter of curiosity. Count 

 Wingersky is said to have [jlanted a great many trees of A. saccharinum on 

 his estates in Moravia, and to have drawn olF the sap from them at the age 

 of 25 years, in order to make sugar. He succeeded in procuring a very good 

 sugar; but, in consequence of drawing sap from the trees every year, they 

 became sickly, and soon afterwards died. 



Soil and Situation, Projja^ation, Sfc. The same soil may be recommended 

 as for A. ;;latanoidcs ; but, as the species is considerably more tender, it 

 requires a more sheltered situation. In British nurseries, it is always raised 

 from American seeds. 



statistics. The largest tree in the neighbourhood of London is at Purser's Cross, where it has .it-

 Knights, 25 years planted, 21 fl. high ; in Hcrefonishire, at E.ist lor Castle, 14 years pl.intcd, .'jO fl.

 Saxony, at Worlitz, 60 years planted, and .W ft. high. In Austria, at Kopenzel, near Vienna, ti 

 years planted, and 14 fl high. In Bavaria, in the Botanic Garden at Munich, 20 years planted, and 

 S ft. high. In Cassel, at Wilhelmshoe, 24 years planted, and .50 ft. high. Some of the largest 

 sugar maples in America, according to Mr. Douglas, arc on Goat Island, at the Falls of Niagara. . 



Commercial Statistics. In the London nurseries, plants cost 2*. each, and 

 seeds 2s. per ounce ; at BoUwyller, plants are 1 franc 50 cents each ; and at 

 New York, 15 cents a plant, and seeds 2 dollars 25 cents per pound.

 I'arieties. 



X A. P.2 Jldvavarkgafa. The i/cllow variegated Si/camorc, or Costorphine 

 Plane with leaves variegated with yellow. — The original tree stands 

 near an old pigeon-house in the grounds of Sir Thomas Dick 

 Lauder, Bart., in the parish of Costorphine, near Edinburgh. Seeds 

 of this variety, sown, have produced plants with green leaves; but in 

 some of the plants the footstalks of the leaves were of a yellowish 

 green colour, and this colour was partaken of by the leaf: in the 

 other plants the petioles were strongly tinged with red, and the 

 leaves were of a darker green than those of the first-mentioned 

 plants.
