In 1854 Miss Caroline Plummer bequeathed to the Salem Athe- 

 naeum $30,000, to be expended in the erection of a suitable building 

 to contain the Library of that Institution; granting liberty, also, to 

 have the rooms occupied Tor meetings of literary and scientific so- 

 cieties, and for the deposit of works of art and natural productions. 

 She moreover provides, that in case the Library of the Athenaeum 

 should ever become a public library her bequest should not be for- 

 feited ; evidently designing that the building erected from the proceeds 

 of her legacy should be the seat of letters and science in this place. 



Upon the completion of the building in 1857, the following propo- 

 sals were agreed upon by both Societies at meetings held in April of 

 that year : 



The Proprietors of the Salem Athenaeum agree 



1st. To allow the Essex Institute to use the rooms on the lower 

 floor of PLUMMER HALL, for any purpose consistent with the terms oi 

 Miss Plummer's will.
