J, 1923, work was completed on the greenhouses of the Summit
Pnction Gardens. Three of the old poultry houses were used
fose after modifications and additions. Land was cleared and

work had progressed sufficiently, I was authorized to make a
tington, D. C., to visit the Department of Agriculture, and
a large number of valuable plants and brought them back to

oduction Gardens. Shortly afterwards a number of plants
were dotd to the gardens by the District Quartermaster at Pedro

plants and seeds were received both from Washington and

and plants of the local flora were also collected for propagating

CITRUS.
local and hardy sour orange was used for stock and a large quantity
were planted on which to bud desirable varieties of Citrus. Most
o is stock is still rather small for extensive budding. All sufficiently
l stockplaits, however, are being used and by next year a consider-
a number of budded trees will be available. A collection of about
3 iferent Citrus relatives were received from Washington, mainly to
etd out for their possibilities as stockplants. They were all planted
a special field where they can be kept under surveillance.

MANGOS.
e local mkngo has been used for seedling stock, and several thous-
young, sturdy plants were grown. At the present most of these
vbeen budded, and the growing buds are in very fine condition.
Adeal of budwood was received from Florida through the Depart-
t of Agriculture at Washington. In all cases this budwood did not
st p well. It was possible, however, to save practically enough

orchard has been commenced at Summit. At the present timb

Rice.-In cooperation with the Bureau of Cereal Crops, of the Depart-
ment of Agriculture, Washington, 25 selections of rice were planted. This
experiment is in continuation of selection work commenced at Porto
R o and Santo Domingo in 1918. All of the selections were closely
.noted as to growth and yield and are now again planted for further tests.
Last year's tests showed R. D. 148 and P. R. 358 as the most promising.
It is hoped by continual selection to establish a pure and high-yielding
strain of a non-irrigated rice suited to our climate.

LEGUMINOUS COVERCROPS.
Tests are being run with the planting of leguminous covercrops. All
of the following cowpeas grew satisfactorily: Brabham, Early Buff, Groit,
Victor, making a luxuriant growth and maturing seeds.
The following velvet beans were planted: Tracy's Early, Bush Velvet,
Porto Rican Velvet Bean, Early Arlington, Georgia. There is no apparent
difference in their value as a luxuriant covercrop; they all produce an
immense quantity of green matter, of value as a green manure, as protein
cattle feed, and as a covercrop, easily coping with and keeping down the
wild weed vegetation.
None of the following Soy beans grew to satisfaction, possibly on
account of lack of proper inoculation; Biloxi, Laredo, Peking, Tokio
Virginia, Wilson.

FORESTRY.
A very large number of trees have been grown, some of value as orna-
mentals, others as important shade or timber trees. In many regions of
the Canal Zone the lands have been denuded of all forest growth, many
pastures being almost without trees. Every day the forests on large
tracts of land is being cut down to give room for the planting of bananas.
With such conditions prevailing the question of tree planting becomes an
important one. Several of the more valuable native trees are in course
of being propagated at the Summit Gardens. Likewise a number of
foreign trees were introduced. Among the more important of these are
such as the Bambus balcooa, one of the Bambus so extensively used in
the Far East for building purposes. It will grow canes 70 feet long and is
making a rapid growth at the Summit Gardens. The rapid growing
Australian trees are represented by Eucalyptii; Grevillea robusta and
Casuarina equiselifolia, all of which should do well on our beaches in
exposed locations. Among the good timber trees which have been
