with this difference, that the tree suffering from branch disease 

 is firm in the ground. Patches of blacl^ latex will probably be 

 seen on the trunk and branches. 



Remedy. 



The only thing to be done is to cut back the unhealthy portions 

 of the tree some 3 inches into the healthy wood, and spray with 

 Bordeaux mixture, made as follows : — • 



Copper Sulphate ... ... 3 lbs. 



Lime ... ... ... 3 lbs. 



Water ... ... ... 45 gallons. 



Dissolve copper sulphate in I or 2 gallons of hot water in a 

 wooden or earthen vessel, stir until thoroughly dissolved, then add 

 about 2/3 of the 45 gallons. Slake the 3 lbs. of lime slowly in the 

 remaining I/3 of water; strain the lime water to get rid of all 

 grit. Add the milk of lime to the copper sulphate slowly, stirring 

 well. Do not mix more than is required for immediate use, as 

 it will not keep. Be careful not to use metal vessels for this mixture. 



Spray the affected tree, together with the surrounding ones, 3 

 separate times at intervals of about 3 days. 



Another equally good application (kept at all chemists) is 

 Arsenate of Lead mixed I to 99 of water. Spray the tree affected 

 thoroughly three times at intervals of 3 days each. This preparation 

 is in a paste in bottles and very easily mixes with the water. A 

 weak solution of Sulphate of Copper in the proportion of I to 20 of 

 water is to be added to the above mixture. All solutions containing 

 Sulphate of Copper must be mixed and carried in wooden or earthen 

 vessels. 



Root Disease: Fomes Semitostus. Detection. 



H. As far as I know, there are three signs of this disease : — 



(1) . The dried-up appearance of the tree, caused by the 



cobweb threads round the roots cutting off supplies. 



(2) . The loose hold the tree has in the ground, which 



can be detected by shaking the tree. 



(3) . A sunken-in appearance on one side of the stem low 



down on the side attacked. 



Remedy, 



The only thing to be done, if the tree is not already dead, is to 

 remove carefully all the earth from the roots with a pointed stick 

 (do not allow changkols to be used) right down to the end of the 

 tap-root, and cut into the roots with a knife to see if they are healthy 

 or not. The affected roots, when cut, will be found to have rotten 

 bark, discoloured wood, and will give no latex. Cut off the diseased 

 portions with about 4 to 6 inches of the healthy root, and apply tar
