Such an arrangement provides for a wind-break 90 feet wide around 
the outside of the plantation, in which the conifers shall form solid 
rows, separated the first few years by nurse trees, whicl: should not be 
permitted to remain long enough to weaken the lower branches of the 
conifers. Had such a wind-break been piaced originally to the south of 
the Brookings plantation, the damage apparent there could not have 
occurred. 
In the second series of one-sixteenth acre plats, Boxelder was used 
as a nurse tree, and various hard woods and conifers were intermixed. 
A few of the plans, with result of count made in the first week in J aly, 
are given herewith. 
One-sixteenth acre, 1 by 1 foot, 2,722 trees.

In this plat it was the purpose to secure a close stand of conifers and 
to avoid all cultivation. The Boxelder was designed to shade the soil, 
and thus prevent weed growth until the conifers were well rooted, 
when it was to be cut out. It was found necessary to hoe the plat 
twice, despite the close planting. The count resulted: 864 Boxelder, 
375 Artemisia, 139 White Spruce, 16 Scotch Pine, 10 Cherry, and 14 
Oak, or 52 per cent of a perfect stand. It will be noted that the count 
reveals more Artemisias than the plat calls for; doubtless through an 
error in planting.
