40 
Scotch Pine and 93 Green Ash were alive in the plowed portion of the 
strips, and 143 Scotch Pine and 83 Green Ash in the unplowed portion, 
a total of 20 per cent of the whole number set in the spring. 
PLANTING IN GRASS. 
In the spring of 1896 a plat of one-half acre was planted in the 
unbroken grass land, no preparation whatever having been given 
the plat. The land is on the crest of the hill and is unfit for cultiva- 
tion, the soil being a gravelly clay underlaid with limestone. Blue joint 
(Andropogon sp.) and other bunch grasses make a good growth in it. 
The trees were set as near 4 by 4 feet as possible without marking the 
land, and the holes were dug without disturbing the grass cover unnec- 
essarily. The ground was so full of stones as to make planting diffi- 
cult. One thousand two hundred and nine trees were used—915 Scotch 
Pine and 294 Rock Pine—both in good condition at planting time. On 
the 17th of June 80 per cent of the Scotch and 97 per cent of the Rock 
Pine were alive, and on October 27, 1896, 60 per cent of the Scotch 
and 21 per cent of the Rock Pine survived. In the spring of 1897 the 
Scotch Pine were replanted, and on June 30 the count resulted in 726 
Scotch Pine and 60 Rock Pine. In October, 1897, a count resulted 
in 673 Scotch and 26 Rock Pine, 58 per cent of the original planting. 
The trees seemed to be well established, many of the Scotch Pine having 
grown over 12 inches during the season. 
This experiment promises to be a success, since 58 per cent of the 
number that were originally planted survived the second summer. 
Compared with either the underplanting noted above, or the field 
planting which follows, this planting in the unbroken grass lands cer- 
tainly gives very favorable indications. It should be observed, how- 
ever, that the grasses in this rocky soil do not form a thick sod, as is 
the usual condition in the prairies. Professor Mason writes of this 
plat, under date of June 30, 1897, ‘“Sumach is growing up thick in 
places, forming a good nurse crop for the pines (Scotch). In fact, they 
are making a better growth here than in any other plat. Some have 
grown 18 to 20 inches this season. The Rock Pine were not replanted 
in this plat, and the last year’s trees do not seem to be growing well.” 
It has been observed at other stations that wild plants of the Rock 
Pine (Pinus ponderosa scopulorum) are difficult to establish and of slow 
growth the first few years. 
FIELD PLANTING. 
In April, 1896, a plat of 1.11 acres, occupying the crest of a ridge, 
soil very thin, clay loam mixed with gravel, with gravel subsoil on 
limestone, was planted to the following species: 99 Bur Oak, 99 Iron- 
wood, 391 Bird Cherry, 607 Donglas Spruce, 499 Norway Spruce, 
697 Rock Pine, 782 Scotch Pine, and 3,128 Jack (Banksian) Pine. The
