twenty inches in height when set. The instructions sent out by 

 the Department were to set the pines alternately with deciduous 

 trees in rows two feet apart, the trees to be two feet apart in 

 the rows. We thought this planting would be too thick, so we 

 set the rows four feet apart, placing the trees two feet apart in 

 the row. Some of the planting was done by alternating the pines 

 with our common forest trees, such as box elder, elm and green 

 ash. Another part of the plantation was set alternately with 

 wolfberry (Symphoricarpos occidentalis), but rather more than 

 half of the ground was set to the pines alone. The planting was 

 done in the common way. The seedlings as taken from the box 

 had their roots dipped in a puddle of clay and were immediately 

 heeled in in mellow ground. The planting proceeded at once, 

 the trees being taken in small quantities to their permanent lo- 

 cation, taking care to keep their roots carefully covered. We 

 took special pains to set the seedlings firmly in the ground. 



The trees have received only ordinary cultivation, such as 

 might be expected on a rented farm. The result has been a fine 

 stand of trees. The Scotch pine are now from four to six feet 

 in height ; the Austrian pine about half as high ; the Pinus 

 ponderosa, which were much the largest on the start, being still a 

 little larger than the Austrians. The best results were obtained 

 in the pure plantation of pines where there was neither nurse 

 tree nor shrub. The pines set with nurse trees have not done so 

 well, but they have done far better than those set with the wolf- 

 berry. The trees are far too thick for a forest. The percentage 

 of loss during the first year on the Pinus ponderosa was far 

 greater than on the other pines, but those surviving look very 

 hardy and thrifty now. 



Among the material set for experimental purposes this sea- 

 son are the following: Spiraea prunifolia, lilac Senator Vollard, 

 Syringa Persica laciniata, Hippophae rhamnoids, Salix alba, 

 Philadelphus microphyllus. Clematis paniculata and Lonicera 

 sempervirens.
