cream, when it is immediately injected into the burrow so as to fill 

 it entirely. It is left there for several hours, or in case of wet soil, for 

 a day, when it can be dug out, care being taken not to break the 

 mould.

Fumigation with tobacco dust, usually effected against the adults 

 of Psylla, also acts as a preventive, benefiting the crop of the following 

 year. The author has obtained good results in laboratory experiments 

 in fumigating against the nymphs, and his assistant, I. I. Yankin, has 

 used this method with success against the larvae of Psylla and Aphid s 

 in orchards.

The general view recently held by different authorities was that 

 the fauna of deserts is very poor and plays no important part in the 

 formation of the soil in them. This view has imdergone a radical 

 change since 1908, when the investigations of the soil in Tiu'kestan 

 and Transcaspia were begun, and it is now recognised that animals 

 burrowing in the ground are important factors in the process of 

 formation of soil. 



This article describes the author's observation as regards termites 

 in this connection which were carried out in the Starvation Desert. 

 Province of Samarkand, during 1908-1915. 



Five species of termites are known to occur in Turkestan, viz., 

 Hodotermes turkestanicus, Jac, H. vagans septentrionalis, Jac, 

 H. angerianus, Jac, H. murgabicus, Vas., and H. baehnanianus, Vas., 

 of which the fijst two are the best known. The effect of these insects 

 on the character of the soil is discussed at length.
