5. When about 25 years old, they may be kept at the rate of 300 per acre, 

 but when old the walnut covers so much ground that an acre would be shaded 

 all over by about 20 trees. 



ASH. 



1. Ash trees will be 16 inches in diameter on the ground and 30 feet high 

 at 25 years, and will begin to have a marketable value long before that for hoops, 

 poles, etc. 



2. The wood is as valuable as pine, and is worth $20 per thousand feet, 

 board measure. 



3. The seed must be kept in damp sand during winter, and be sown in 

 spring. It takes sometimes as much as 18 months to germinate. It thrives 

 much better when sown where the trees are to stand. If sown in bed, transplant 

 from the nursery at two years. Plant in rows four feet apart and four feet in the 

 row. Then thin every two or three years, till the trees are sixteen feet apart each 

 way. Sow corn between the rows during the first years, to shade the young trees. 



4. Ash requires rather damp, and deep, rich soil. It will never thrive on 

 dry^ hard and poor soil. 



5. Keep 150 to 200 trees per acre. 



MAPLES. 



1. Maple is a slow grower. It will be 24 inches in diameter on the ground 

 and 50 feet high at 45 years, but it has a marketable value sooner than that. 



2. At about 15 years the rock, or sugar, maple will be 8 inches in diameter, 

 and can be tapped for the sake of getting its sap to make sugar. From that age, 

 the maple bush will yield a good crop of sugar every year, the sap containing 

 about 5 per cent, of sugar. It may, at the same time, be thinned for fire-wood. 

 When older, it is employed for wood-work, and is worth $15 per thousand feet, 

 board measure. As fire-wood, it is worth $2.50 per cord. 



3. The seed ripens in autumn, and should be sown at once. Transplant 

 at two years and treat as the ash for transplantation. The plant soon shades the 

 ground with its luxuriant foliage, so that the soil does not need to be cultivated 

 very long. 



4. Hilly, dry, stony or gravelly soil is what the maple requires. 



5. On the average, maples may stand at the rate of about 200 trees per acre. 



Of course, the measures and prices given in these answers are only approxi- 

 mative and may vary pretty much in different districts and according to the con- 

 ditions of climate, soil, market, etc.
