millimetres, while at Erivan, 18 kilometres nearer the moun
tains to the east, it is 315 millimetres.1 There is most ram as
a rule in the spring months, April and May, whereas there is
usually very little later on in the summer, in July, August,
and September. The following table gives the mean
temperature in degrees Centigrade and the mean rainfall in

At Echmiadzin it rams rather less in summer, and still
less farther out on the plain ; but it may vary a good deal
from one year to another. In 1922, for instance, a great deal
of ram fell all through the summer ; at Erivan the rainfall in
June was 68 millimetres, in July 3 5 millimetres, in August
5 8 millimetres, and in September 25 millimetres. None the
less there is generally too little ram throughout this region
for the land to be cultivated without artificial irrigation ;
indeed, it is impossible even with crops like wheat, which
one would expect to ripen in the early summer, while there
is still, as a rule, a good deal of ram. What is still more
remarkable is that not only the plain, but all the mountain
slopes around are naked and treeless ; there is not a tree
to be seen except in places reached by the irrigation canals.
The rainfall is not so insigniflcant, however, that it alone

millimetres; in Delijan, to the north among the mountains, it is 521 milli-
metres, and in Leninakan 408 millimetres.
