The Federal Government has purchased the nut arboretum 

 of William C. Bixby, at Baldwin, L.I. The trees include black

Professor R. A. Emerson, of Cornell University, is spending 

 part of his sabbatic leave in Yucatan with J. H. Kempton, of the

 Emerson will visit laboratories of genetics in California and
