PRACTICAL ARBORICULTURE 245 
IN NEW ENGLAND. 
In White’s Park at Concord, N. H., are quite a number of fine young trees 
in perfect health. 
At Manchester there are many of quite large size, the true speciosa; some 
are 16 inches in diameter. These were brought from Indiana. 
At a point on the Maine Central Railway, in latitude 45, there is a fine 
specimen of Catalpa speciosa some 14 inches in diameter. At Rockland, Me., I 
found several small trees. 
At Arnold’s Arboretum, Boston, are quite a number of Catalpa trees in 
a very unfavorable and exposed situation, which are in healthy condition and 
have made fairly good growth for their situation. 
At the home of Mr. Arthur J. Marble, 36 Birch street, Worcester, Mass., 
is a Catalpa speciosa seventeen years old, which is 78 inches girth at the 
ground, 68 inches girth at three feet height, and 72 inches girth at seven feet 
from ground. This tree is grown for shade, being 4o feet high, with a spread 
of branches 35 feet. 
SOUTH DAKOTA. 
There are many good trees of Cata/lpa speciosa in Sioux Falls. 
GENEVA, NEB. 
Measured Catalpa speciosa 48 inches girth, 16 inches diameter, 12 years 
growth, 35 feet in height. 
PUEBLO, COLO. 
On the grounds of the C. F. & I Co.’s hospital are several Catalpa trees 
12 inches and upward diameter; doing well. 
Catalpa speciosa trees at Audubon Park, New Orleans, La., planted in 
1890; now sixteen years growth; time of planting certified, which are 26 inches 
diameter. 
SOILS SUITED FOR CATALPA SPECIOSA. 
This tree seems to adapt itself to almost every character of soil, growing 
well in clay, sand, limestone soils, etc., but its roots find abundant nourishment in 
sandy loam, and even in pure sand, and are able to penetrate such soils more 
readily than stiff clays. 
Experience has shown that soils of almost pure sand, although they may 
be favorable for agricultural crops, are specially adapted for the Catalpa tree. 
Where a stratum of impermeable hardpan exists beneath the surface soil, 
it checks the roots for a short time, but the tap roots gradually penetrate this 
hardpan. 
Rough limestone hills with abrupt slopes are not suited for Catalpa cul- 
ture. It is more profitable to plant in tracts which are capable of being culti- 
vated. 
Rolling lands, even in mountainous districts, which may be plowed, will 
produce good timber growth. 
Strongly alkaline soils can not be recommended; few trees will thrive in
