slips on my farm for a windbreak, and I have had such good success 

 with them that I have planted more from year to year. I now have 

 four acres of this kind of windbreak grove around my buildings, 

 yard and apple orchard. I have trees of this kind grown from slips 

 eight inches long and one-third of an inch thick, planted fourteen 

 years ago, which now measure seventeen inches in diameter, and 

 are from forty-five to fifty-five feet high. I challenge any farmer 

 or tree grower in the state to show better results. Considering the 

 age of my trees, I believe there is not a better windbreak grove in 

 the state. During the past four years I have taken all my summer 

 firewood out of this grove, four or five cords or more each season. 

 I cut this wood and pile it up green in the woodshed ; it is soon dry 

 enough to burn, and it makes a splendid heat. 



I will now explain my way of planting the Norway poplar grove. 

 I take the limbs of the last year's growth and cut them about nine 

 or ten inches long. Some limbs make four or five slips. I plant 

 these slips four feet apart one way and five feet the other way, and 

 push them into the ground five or six inches deep. If the ground is 

 very hard I take a piece of iron and shove it down first, and then I 

 put in the slips. The ground should be plowed in the fall and well 

 pulverized so that the moisture will be held. I work the ground 

 the same as for corn. The ground should be kept clean of grass 

 and weeds so as to give the little tree a chance to grow, and it will 

 grow. I take care of the trees in this way for three years, when they 

 will be large enough to shade the ground so that neither grass nor 

 weeds will erow.

Four years ago this spring I planted 500 slips. These trees now 

 measure on an average thirty feet in height, and are from four
