says that its best dimensions are attained on rich, deep, bottom lands 
which are inundated during several weeks each year. e orange 
colour of the young branches is given as a ready means of dis- 
tinguishing the tree from other kinds. ough, “ American W oods,” 
ill, p. 64, gives a description of the wood and refers to the nuts, 
which are said to possess a delicious flavour, and always to find a 
ready market. It might be tried under similar conditions to C. alba. 
THe Mocxer-nut Hickory (Carya tomentosa, Nutt.) Like 
several of the other hickories this species produces timber of first- 
rate quality, whilst its nuts constitute such an important article of 
trade that it is grown for their production as well as for timber. 
It is found between 90 and 100 feet in height with a girth of from 
9 to 12 feet, inhabiting the middle and southern States from the 
coast westwards to Nebraska and Kansas. Its maximum growt 
takes place in rich upland valleys and on gentle slopes; towards the 
more northerly parts of its range, it is confined to the neighbour- 
hood of the coast. The best specimen at Kew may be seen near 
the Azalea Garden. It was planted in 1872, and is now 49 feet 
high, with a girth of 2 feet 54 inches at 5 feet from the ground. 
The leaves of many of the Caryas, and of this one in particular, are 
very effective in autumn, for they assume a rich golden colour 
previous to falling. This desirable quality suggests them as goo 
subjects for massing in places where landscape effect has to be 
studied. 
AMERICAN Oak (Quercus spp.). Although some 50 or 60 
species of Quercus are natives of N. America, very few are ever 
49 per cent. of the total annual cut of hardwoods in the southern 
Appalachian region. Q. alba is the most important tree im the 
group, which includes such species as Q. macrocarpa and Q. bicolor. 
The principal uses for white oak appear to be ship and waggon 
building, furniture, cross-ties for railroads and staves for barrels, 
White oaks, as a rule, grow unsatisfactorily in this country, hence 
the necessity for exercising caution in the formation of plantations. 
Other classes of American oak are known as “red oak” and 
“black oak.” Some of the species which produce these classes, 
grow satisfactorily in this country, but the timber is inferior to that 
of the white oak, and might be classed with that of the Turkey 
oak for quality, rather than with that of the British species. 
The following species, however, deserve a trial in our woods. 
Tae Burr Oax (Quercus macrocarpa, Michx.). It is probable 
that this species wil prove more satisfactory than others of the
