liked by them, and when the flowers are out, which are of a 
yellow colour, this tree has great beauty. The leaves die to a 
` golden-yellow colour in autumn, which produces a good effect _ 
at that season.— Linnzeus recommends it for walks and plant- 
ations, as yielding a juice from which sugar may be made, if it 
be wounded in the winter, and as cutting out into a fine white 
wood, fit for the stocks of guns, the joiner, and the turner, 
and answers all the purposes of the Sycamore. The raising of 
this tree for use and ornament should not be neglected.

40 feet. It has some resemblance to the Norway maple when 
the plants are young. The flowers are yellow, disposed in short 
compound corymbs, composed of imperfect hermaphrodite and 
perfect male flowers, the anthers being abortive in the first and 
perfect in the last. From this tree the inhabitants of North 
America make a very good sort of sugar in large quantities. 
It is very probable that the Americans make sugar from many 
species of maple, particularly 4. rubrum and Negúndo fraxini- 
folium. The juice is obtained by tapping the trees; warm days 
and frosty nights are most favorable to the plentiful discharge 
of the sap. A hole is made in the tree in an ascending direc- 
tion by an augur, and a spout is introduced about half an inch, 
which projects from 3 to 12 inches; it is generally of sumach 
or elder. The sap will sometimes flow 6 weeks, according to 
the temperature of the weather. Troughs are placed under 
the spouts to receive the sap, which is carried every day to a 
large receiver, from which it is conveyed, after being strained, 
to the boiler. Lime, eggs, or new milk is added to the sap in 
order to clarify it, but clear sugar may be made without any of

these ingredients. ‘The sugar, after being sufficiently boiled, is . 
grained, clayed, and refined in the same manner as the cane 
sugar in the West Indies. The sooner the sap is boiled the 
better. It should never be kept more than 24 hours. The 
quality of maple sugar is superior to that which is made in the 
West Indies from the cane, and it deposits less sediment when 
dissolved in water. It has more the appearance of sugar-candy, 
“ The sugar prepared from the sap of this tree is one of the 
greatest conveniences to the inhabitants of the Western Coun- 
ties, is equal to any other sugar, and procured with little 
trouble.” (Pursh.)
