72 THE SCHOOL BOOK OF FORESTRY 



No seed or tree stock can be imported. Further- 

 more, all the new species of trees, cuttings or 

 plants introduced to this country are given thor- 

 ough examination and inspection by government 

 experts at the ports where the products are re- 

 ceived from abroad. All diseased trees are fumi- 

 gated, or if found diseased, destroyed. In this 

 manner the Government protects our country 

 against new diseases which might come to our 

 shores on foreign plants and tree stock.
