156 First Report on Economic Zoology. 
As Lower Egypt is not troubled by these insects, I have applied in vain 
to the School of Agriculture at Cairo for information as to the best method 
of getting rid of them. I may add that we have planted a good number 
of Casuarina trees, which are supposed to be proof against the attacks of 
White Ants ; but they eat the trees with the greatest impartiality. 
I have the honour, therefore, to suggest that you will have the kindness 
to forward a copy of this letter to the proper quarters with a request that 
I may be supplied with any information there may be on the subject, or 
that I may be referred to any books or papers on the same. 
I am, etc., 
(Signed) Gleichen, Major, 
Assistant Civil Secretary for Governor- General. 
Cairo, Oth August, 1901. 
To The Marquess of Landsdowne, K.G., etc., etc. 
My Lord, — I have the honour to transmit to your Lordship 
herewith copies of a note which I have received from the Civil Secretary 
to the Soudan Government, asking for assistance in procuring information 
as to the best means for combating the ravages of the White Ant, which is 
extremely destructive in the Soudan. 
I am informed that, in certain parts of America, the White Ant is very 
prevalent, and that considerable attention has been directed to this subject 
by the Department of Agriculture in the United States. It is probable 
also that the Colonial Office are in possession of valuable information, and 
more might perhaps be obtained from the Horticultural Gardens at Ivew. 
I should be most grateful if your Lordship would render me any 
assistance which is possible, in obtaining such information as may be 
available, for the use of the Soudan Government. 
I have, etc., 
(Signed) Rennell Rood.

To the Director of the Royal Gardens, Ivew. 
Sir, — I am directed by the Marquess of Landsdowne to transmit to 
you the accompanying copy of a despatch from His Majesty’s Acting Agent 
and Consul-General in Egypt, relative to the ravages committed in the 
Sudan by the White Ant. 
I am to enquire whether the Director of the Royal Gardens can furnish 
any information on the best means of combating the ravages of these 
insects. 
I am, etc., 
T. H. Sanderson.
