cones require two seasons to reach maturity, ripening in 

 autumn. This pine is very hardy. In many places in the 

 west, fine trees may be found growing in the poorest soil un- 

 der the most adverse conditions of drought and exposure. 

 It is a promising tree for forest plantations. It occurs 

 throughout the Black Hills." 



A. Norby, Madison, S. D., Lake county, east central, re- 

 ports as follows on his twenty years' experience with this 

 tree: "First among pines I would put the Bull or Black 

 Hills pine (Pinus ponderosa). I have a row of this on the 

 top of a hill, now averaging about twenty feet high, straight 

 and thrifty as a pine should grow. Never have they showed 

 a dead limb or lost their leader. The color is a light green 

 the year around. If you think it too much work to cultivate 

 or even break the ground, just stick it out on the sod, and if 

 it starts the first season, it will come on and make a good 

 thrifty tree, showing that it does not mind drouthy spells or 

 sod bound sites like most other evergreens. Like all pines, 

 it requires plenty of room and sunlight. Running its roots 

 far and deep, it must be handled right in the nursery to trans- 

 plant well. The ponderosa is the only pine found in the 

 Black Hills and Nebraska, where it occupies the dry table 

 lands in the northwestern portion, where it has been growing 

 for ages past under the most adverse conditions."* 



A. Norby, Madison, S. D., wrote in January, 1904, as fol- 

 lows: "We are fortunate in having evergreens native of our 

 state grand trees through centuries adjusted to conditions far 

 more trying to sylvan culture than this section, and admir- 

 ably adapted for windbreaks. 



"Look at the ponderosa pine in its native habitat in the 

 semi-arid region east of the Black Hills, in this state and 

 Nebraska, where it extends down to the icoth meridian. 

 Fine single specimens are found in the tough prairie sod and 

 groves cap the dry rocky hills where a deciduous tree could
