highways is $1,146 a mile. How many miles of such 

 roads might be made at a cost of a single battleship, cost- 

 ing $10,000,000 ? 



650. The annual expenditures in our War and Navy 

 Departments are $160,000,000. If these were reduced 

 one-half how many miles of roads might be made into 

 improved highways annually with the saving? 



WHY GOOD ROADS PAY. 



They save horse flesh and time. Many times larger loads may be hauled over 

 good roads than over poor ones. 



651. The little city of Haslar, in the Hartz Mountains, 

 owns a spruce forest of 7,000 acres, which by careful 

 management permits an annual cut of 7,300,000 square 

 feet of wood per annum. The city macadamized the 

 roads leading through the forest at an expense of $25,000. 

 The average cost of hauling 1,000 feet B. M. on the old 

 roads was $2.70. On the new roads the cost is $1.70. 

 What is the income on the investment in new roads from 

 the saving in hauling alone?
