AOH 



a point, in Celtic. The name is nsed to desig- 

 nate this genus on account of the wood having 

 formerly been much sought after for manufac- 

 turing into heads of pikes and lances. Linn. 

 23, Or. 1, Nat. Or. Acerdceoe. For the most 

 part beautiful trees, of considerable size, gene- 

 rally employed in forming avenues or the back 

 of shrubberies. The soil they delight most to 

 grow in is open sandy loam, in which also 

 cuttings will strike freely in the open air ; or 

 by layers put down in the autumn they may 

 be increased ; but all the best plants are 

 obtained from seed, which should be sown 

 soon after gathering. From the sap of A. 

 saccharinum and other species, the North 

 Americans make a considerable quantity of 

 very good sugar. Synonymes: 1, A. erio-

 for park and pleasure garden scenery, of which
