it was a youth of 1500 summers. Thousands of the trees 

 now standing in the Sequoia National Park were growing 

 during the time of Caesar. Hundreds were flourishing while 

 Babylon was in its prime. Several are older than the Pyra-

State forests. The state governments are also beginning 

 to set aside forests. Thirty states have a forestry depart-

 with an area of three and a half million acres. New York 

 State leads with i ,600,000 acres ; then comes Pennsylvania 

 with nearly a million; Wisconsin with 400,000; Michigan 

 with 231 ,000 and other states with smaller forests. Fourteen

 whose chief duty is to look after the protection and use of 

 the national forests. Some of the work of the service is 

 done in Washington and some in the national forests. 



The direct care of the forest is intrusted to the ranger. 

 His most important duty is to protect the district in his 

 charge against fires. During certain seasons he patrols his 

 district by means of trails and bridges for the purpose
