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. 
"Opmtia hybrids. Dr. Trabut has a very Interesting 
series of hybrids between different species (0. fipus- 
indiea, 0. tuna, etc.) some of which have very large and 
juicy fruits . 
"Chloris gay ana Is a very valuable grass lh Dr. Tra- 
but?' s estimation. He says that It is very aggressive 
and will of ten 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 haying re- 
markably finely divided leaves and. being almost as 
delicate in appearance as an Adiantum. 
"Saccharum spontaneum aegyptiaeum. This grass is con- 
sidered by Dr. Trabut to be a very valuable sand bind- 
er, which he thinks will be useful in subtropical 
climates like that of Florida. 
"Tecoma Hybrids. 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. oeeidentolis and J?. 
robusta are the species which do best in poorly drained 
land containing alkali. E. punctata 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. algeriensis, 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
