ORNAMENTAL PLANTINCJ. 



Much of the tree planting in the North Platte and South Platte val- 

 leys will be for ornament. Towns and cities should encourage street 

 planting. The plan that Denver has just inaugurated, of maintaining 

 a city nursery to supply its own forest-tree stock, is excellent. School 

 and church grounds offer opportunities in ornamental planting for 

 village improvement societies. Concerted effort along these lines will 

 add greatly to the attractiveness of the country. 



The practice of planting trees along roadsides has much in it that is 

 commendable. In some States, notabl}^ New York, Pennsylvania, and 

 Massachusetts, such planting is encouraged by a partial rebate of 

 taxes on land thus improved. Not only do roadside trees add to the 

 attractiveness of the farm, but they have a positive economic value in 

 the protection they afford to the crops and farm animals and in the 

 products they yield. The chief objection urged against roadside 

 planting is that trees rob the soil and decrease the yield of adjoining 

 crops. Where this objection holds it is simply a matter of choosing 

 between the slight loss to crops and the advantage of having the trees.
