Eucalypts in African Steppe Regions, Notes on the Utilisa- 

 tion of West Australian. By Dr. L. Diels (Not. Edmg. Bot. Berlin, 

 Bd. IV., pp. 67-70 ; August 30, 1903).— Practically a report on the author's 

 experience of four species in West Australia, as regards climate and other 

 conditions, and a suggestion that an experiment in the region referred to 

 may succeed. — H. M. W. 



Eucalyptus Hybrids. By Dr. Trabut (Bev. Hort. July 16, 1903, 

 pp. 325-8 ; 3 woodcuts). — Description and illustrations of several 

 interesting hybrids : E. Rameiiana (E. botryoides x rostrata), E. gompho- 

 cornuta (E. gomphocephala x cornuta), and E. BourUeri (E. Globulus 

 x ?) ; all three spontaneous hybrids due to mixed collections. — C. T. D. 



Eulophiella Peetersiana. By Ed. Andre (Bev. Hort. September 1

Experiment Station Work. (U.S.A. Dep. Agr. Off. Exp. Stn., 

 vol. ii. No. 2 ; 1903 ; figs.). — The results of experiments in : — 



1. When to cut forage crops. 



2. Lippia nodi flora as a lawn plant. 



3. Pithiness in Celery. 



4. Irrigation of Strawberries. 



5. Farmers' fruit gardens. 



6. Management of orchards. 



7. Tropical and sub-tropical fruits. 



8. China Asters. 



9. Preserving Sweet Potatos.

1. Analyses are given of the chemical composition of various feeding 

 stuffs at various stages of growth, but the author points out that whole- 

 someness, digestibility, and other factors besides chemical composition 

 must be taken into account in determining the comparative value of 

 different foods. 



2. Lippia nodiflora, or Fog Fruit, is described as having a remarkable 

 capacity for resisting drought and extremes of temperature, and as 

 possessing special advantages as a sand and soil binder. They report 

 from the Arizona station that during the summer of 1902 Lippia main- 

 tained itself for eight months on the Mesa with less than 2 inches of rain.
