ing in the nursery, that in the course of one, two and three years 
such trees would attain sufficient growth to become suitable for 
street planting. The experience of caring for a tree in the nur- 
sery is estimated at about 10 cents per year, the nursery being 
provided with connection with the water main has prevented any 
loss of consequence amongst the trees planted in the nursery. 
With the development of the Forest Lawn Nursery, there 
will be ample room to plant even smaller sizes which by cultiva- 
tion will attain the necessary growth, and obviate the necessity 
of the purchasing of the larger sizes and more expensive trees 
in the future. The nursery at Forest Lawn is admirably adapted 
for nursery purposes, being a fine, rich soil of good depth and 
being surrounded by forest trees, except to the south, making 
conditions ideal for rapid growth. The Commission has pur- 
chased some 5,000 seedlings, Elms, Norway Maples, Pin Oaks 
and Gingkos, which it is planting and will plant or transplant 
each year a like number until twenty-five to thirty thousand 
trees are growing from which can be taken each year those of 
proper size to ful the requirements of street tree planting. As 
a full grown tree ready for planting upon the streets is worth a 
dollar at wholesale nursery rates, sometimes more, it can readily 
be seen that there will be a constantly increasing growing value 
to the nursery stock owned by the city, which will enable the city 
to provide its own trees at a less expense than if purchased di- 
rectly from outside nurseries. The Commission has provided 
for drive wells at Forest Lawn, and a force pump with power at- 
tachment, which will enable it to irrigate the growing trees in 
exceedingly dry times. 
The economy of a nursery can best be illustrated by a con- 
crete example in street tree planting. During a dry season, it 
would not be an abnormal loss of ten per cent of the trees planted, 
although the Commission has not lost through its careful plant- 
ing any such per cent, though in its plantings it has replaced 
sets of trees whose loss has been 90% since the original planting 
by others before the organization of the Commission. Each 
tree, upon an average, costs in labor, guard, mulch, excavation, 
filling and tree $2.00 each. The Commission plans to plant four 
thousand trees annually. Procured from outside nurseries, it 
invites a larger percentage of loss. Ten per cent of 4,000 trees 
would be 400 trees, at two dollars each, would be $800.00, to 
which should be added the lost growth of a year, in the most
