I do not know the extreme minimum temperature at Biskra, 
but the lowest in the part of Queensland above referred to is 
26-4deg. at Boulia in July, 1894. My information for Queens- 
land is obtained from the Meteorological Reports, which are on y 
avaUable from 1st September, 1893, to 31st August 1894 1 
believe this last winter was considered a very cold one throughout 
the colony, and as the Date Palm can stand as low a temperatuie 
as 26deg. it should be safe even at Boulia trom being killed 
by frost. The latitude 'iOdeg. S. to 29deg. S. also indicates 
generally the area in which the suitable temperature is to 
met with. 
R..ixPAi.n._In the above possible 
Queensland the rainfall ranges from om. to 24m. , and in 
westerly portion this reaches the minor limit, therefore § 
the quahiy of the date on account of the f 
air combined with the circumstance that theie is gr 
also. 
AnTiTunE.-Looking generally at West 
rivers and creeks all run to ^ ihgh 
downs between the Gulf of Carpentaria f ^ 
Diamantina and Thomson rivers; so that ^ 
gi-ound must vary from 600ft. to 1400ft. above sea lev - Bu^ 
fo the south-west of Boulia and Wmdorah aiM to he south 
of Thargomindah and Charlevaie the altitude of ^ J 
from sea level to 600ft. From the above figures 
be seen where there is the least likelihood oi frost. 
Som.-The geological formation in the region indicated is 
mesozoic, with desert sandstone on the 
the various watersheds iate'pahn prefers a sandy soil, the 
downs. As apparently the V&te i aim y
