Arbor Day. Twenty-five hundred copies ot a pamphlet on Arbor Day 

 were printed this vear by the State Board ot Agriculture of Massachusetts 

 and mailed to schools, with the request that the day (April 28) would be 

 given some observance by teachers of nature-study and sciences. The 

 pamphlet contains papers on selection of woody plants for school-grounds, 

 how birds effect trees, on certain insect enemies, and on the meaning of 

 Arbor Day. Those interested should write to the Secretary of Agriculture, 

 Boston, and apply for a copy.
