VIII. The HoiiSE Chestnut {J^sculus hijypocastamim). 

 Great trees seem to be rarer in this than in any other 

 of the deciduous forest species in Scotland. There are but 

 three in Mr. Hutchison's table above 15 feet in girth at 5 

 feet from the ground ; and although one reaches 19 feet, 

 this may be not (juite at the narrowest part, as the bole is 

 only 8 feet high. The species seems not to have been 

 introduced in Britain till about 16 20, and may not yet 

 have had time to produce giants.
