Several of the species produce very useful 
timber ; sugar is one of the constituent parts of the sap of 
all of them, and is obtained in large quantities from A. 
saccharinum, in North America. They all prefer a some- 
what sheltered position. ‘The most satisfactory soil is 
one free, deep, loamy, and well drained; the latter is 
desirable ‘with some of the Japanese varieties. 
The varieties of A. ee. and palmatum are well 
worth growing in for conservatory decoration. Pro- 
pagation: By seeds, sown either in autumn or spring, 
covering them not more than a jin. deep; the common 
biter may be sown a while the rarer ones should
