sweeping winds, might prevent that. The difficulty of re-for- 
esting bleak New England coasts, which were originally well 
wooded, is well known. It is equally but probably not more 
difficult to establish forest on an Iowa prairie, with proper 
selection of trees. 
The difference in the composition of the Atlantic and Pa- 
cific forests is not less marked than that of the climate and 
geographical configuration to which the two are respectively 
adapted. | 
With some very notable exceptions, the forests of the whole 
northern hemisphere in the temperate zone (those that we are 
concerned with) are mainly made up of the same or similar 
kinds. Not of the same species; for rarely do identical trees 
occur in any two or more widely separated regions. But all 
round the world in our zone, the woods contain Pines and 
Firs and Larches, Cypresses and Junipers, Oaks and Birches, 
Willows and Poplars, Maples and Ashes, and the like. Yet 
with all these family likenesses throughout, each region has 
some peculiar features, some trees by which the country may 
at once be distinguished. 
Beginning by a comparison of our Pacific with our Atlantic 
forest, I need not take the time to enumerate the trees of the 
latter, as we all may be supposed to know them, and many of 
the genera will have to be mentioned in drawing the contrast 
to which I invite your attention. In this you will be impressed 
most of all; I think, with the fact that the greater part of our 
familiar trees are “conspicuous by their absence” from the 
Pacific forest. 
For example, it has no Magnolias, no Tulip-tree, no Papaw, 
no Linden or Basswood, and is very poor in Maples; no Lo- 
ceust-tree — neither Flowering Locust nor Honey Locust — 
nor any Leguminous tree ; no Cherry large enough for a tim- 
ber-tree, like our wild Black Cherry ; no Gum-trees (Nyssa 
nor Liquidambar), nor Sorrel-tree, nor Kalmia; no Persim- 
som, or Bumelia; not a Holly; only one Ash that may be 
called a timber-tree; no Catalpa, or Sassafras; not a single 
Elm, nor Hackberry ; not a Mulberry, nor Planer-tree, nor 
Maclura; not a Hickory, nor a Beech, nor a true Chestnut,
