nearly spineless leaves and producing enormous heads. 



"Sisal. Dr. Trabut has hybridized the Sisal plant 

 with an unnamed species of Agave from Potosi, Mexico, 

 and has obtained a most interesting series of forms 

 which he says has been studied by an assistant of Dr. 

 Trelease. Dr. Trabut says that the types which have 

 the broadest, flattest and most nearly spineless 

 leaves yield the best fiber. 



"Opuntia hybrids. Dr. Trabut has a very interesting 

 series of hybrids between different species (0. ficus- 

 indica, 0. tuna, etc.) some of which have very large and 

 juicy fruits. 



"Chloris gayana is a very valuable grass in Dr. Tra- 

 but's estimation. He says that it is very aggressive 

 and will often drive out Bermuda grass when in compe- 

 tition with it. 



"Pecan. This nut is coming into favor in Algeria 

 where it does very well and is being frequently plant- 

 ed. On the other hand, Dr. Trabut ' s efforts to popu- 

 larize the grapefruit and avocado have not been suc- 

 cessful, the French appearing not to care for either 

 of these fruits . 



"Boston fern. In his interesting little garden at 

 the Ecole de Medecine Dr. Trabut has some interesting 

 variations of the Boston fern, one of them having re- 

 markably finely divided leaves and being almost as 

 delicate in appearance as an Adiantum. 



"Sacchanim spontaneum aegypiiaeimi. This grass is con- 

 sidered by Dr. TrabuU to be a very valuable sand bind- 

 er, which he thinks will be useful in subtropical 

 climates like that of Florida. 



"Tecoma nybrids. We saw a great many hybrids of the 

 arborescent form (T. stans type) with scarlet, orange, 

 bright yellow, white and rose-colored flowers. This 

 plant seems to be a very popular ornamental in Algeria. 



"Eucalyptus. Dr. Trabut has been experimenting for 

 years with species of Eucalyptus and has obtained some 

 interesting hybrids. He says that E. Occident alis and E. 

 robusta are the species which do best in poorly drained 

 land containing alkali. E. pun data is an especially 

 beautiful species of which we saw a remarkably fine 

 avenue at L'Arba. In a planting made by the Forest 

 Service a few miles west of Algiers the hybrid between 

 E. rostrata and E. rudis, which is known as E. algericnsis, seeds 

 itself readily. No other eucalyptus grown in Algeria is 

 known to do this. Many of the large plantings of eu- 

 calyptus in Algeria have been cut down for firewood, 

 since the war began, but they sprout readily from the
