Dear Sir:- By direction of Messrs. Olmsted, Olmsted & 

 Eliot, Landscape Architects to the Metropolitan Park Commission, I 

 am collecting the material for a forest survey, flora and fauna of 

 the Blue Hills, Middlesex Fells, Stony Brook and Beaver Brook reser- 

 vations. You have kindly offered to assist in the preparation of 

 the flora and I am sending with this a set of maps of the above re- 

 servations and a permit to collect. 



To secure uniformity, brevity and economy of space, abbrevia- 

 tions indicating the following terms are recommended to be used:- 

 c. common; f. frequent; o. occasional; r. rare. 



It is understood that the terms are to have the following meaning 

 when used in referring to plants. 



Common (c) having a nearly even distribution over all surfaces of a 

 similar character, within the area specified. 



Frequent (f) found frequently in masses or as individual plants but 

 not evenly distributed over surfaces of a similar character within 

 the area specified. 



Occasional (o) found only occasionally in different parts of the 

 reservation where the conditions are favorable. 



Rare(r) found only in one or a few places within the reservation. 



If a plant is commom (c), frequent (f) or occasional^) through 

 the area referred to, where the conditions are favorable, nothing m 

 more than the abbreviation an and indication of the locality will 

 be required. If it is common in one locality and not in another this 

 should be specified. The locality for rare plants should be speci- 

 fied ( not necessarily for publication).
