220 EXPERIMENT STATION— BULLETINS. 



C. " Yes, I know it. We can let the young trees grow up along the fences 

 of our fields, and we can plant trees west of our farm buildings ; but then it 

 would be a great deal of trouble and cost a good deal to plant trees, and we 

 should have to wait so long for any favorable results." 



B. "The cost is much less than most persons imagine, and when once 

 started, they keep growing year by year, and before you are aware of it, the 

 little trees have grown upwards and spread outwards. Suppose you were to 

 plow a strip a rod wide and ten or fifteen rods long either in a straight line, 

 in a curve or in an irregular shape. That would not cost much. Then har- 

 row it well, as though you were fitting the piece for corn." 



C. " Then I should have to go to the woods and find some good trees, dig 

 them, cart them to the house, dig deep holes, set the trees, stake them, 

 mulch them, wait a while, see half of them die and the others would look 

 pale and stunted." 



B. "I think you could do better than that. Of course you must arrange 

 the fences so as to keep cattle, sheep and horses away from young trees. Let 

 us see about the plan for a wind-break or for a small grove. You can put in 

 as many kind of trees as you like, the more the better, if you want to try 

 experiments and think you would like to study them and learn their habits, 

 but if you want trees that will grow fast, that are likely to remain healthy 

 and furnish protection, you need only one, two or three species which are 

 the best adapted for the purpose. We can't afford to go to the woods and 

 dig trees. We can buy them cheaper." 



C. " Buy them ! Why, a nurseryman will charge me twenty-five to fifty 

 cents apiece for his evergreens. I can't afford that." 



B. "Procure small trees; they will cost much less ; they can be more easily 

 planted ; will be more likely to live, and after a few years they will very 

 likely catch up and overtake trees which were larger at the time of planting. 

 The foundation of your screen will consist of evergreens. If others are 

 added which are not evergreens, they should not be put in blocks each sort 

 by itself, but mixed more or less in checker-board style with the evergreens. 

 And the evergreens may as well be mixed if no others are planted. You will 

 want to set them in rows, straight, curved or crooked in one way four feet 

 apart and three or four feet apart in the row, so they can be as easily 

 cultivated one way as corn or potatoes. There is little risk in setting too 

 thickly, and the trees will sooner shade the ground. 



"E. Douglas & Sons, Waukegan, Illinois, will send by mail: 



" White pines, 3 years old, @ $1.00 per 100, or $8 per 1,000. 



" Norway spruces, 3 years old, @ 75 cents per 100, or $6 per 1,000. 



" At about the same price you can procure any or all of the following : 

 European larch, white ash, American elm, black cherry, black locust and 

 many others, remembering that for good screens, half or more of the trees 

 should be evergreens rather equally distributed over the ground. W. W. 

 Johnson, Snowfiake, Antrim Co., Michigan, will doubtless send young trees 

 at the above prices. A single row or two rows will make a good screen, but 

 you will be better pleased with a wider strip of trees." 



C. u I will send a postal card right away and get the price lists from these 

 two men. It won't cost much to start a screen in that way. Tell me more 

 about setting the trees, as you seem to know concerning such things." 



B. "The trees arrive about the time you are sowing oats. Open the pack- 

 ages, and place the roots in damp soil in the shade, not forgetting that the
