The possibility of it becoming impossible to grow sissoo on a large scale 

 in Changa Manga has already been referred to in paras. 10 and 16 and conse- 

 quently although it is advisable to continue to try to grow it for the present, 

 the possibility of it becoming absolutely necessary to find a substitute makes it 

 desirable to experiment with other promising trees. 



The best method of maintaining sissoo standards will probably be to clear 

 mulberry and weeds in the coupe after felling so as to prevent the sissoo which 

 springs up freely from seed and rootsuckers from suppression by mulberry. The 

 clearing should be done in strips and will also result in maintaining a proportion 

 of sissoo in the coppice and save it from being completely driven out by mul- 

 berry. For many reasons an admixture of sissoo is desirable, but as explained in 

 paras. 7 and 8 it is not advisable to attempt to maintain sissoo as the principal 

 species. The clearing of mulberry, &c., will therefore be done primarily to obtain 

 young standards and secondly to preserve an admixture of sissoo in the coppice. 

 The cleared strips will require constant attention for 3 or 4 years to prevent 

 the mulberry obtaining the upper hand, and ifc is suggested that they be 100 

 feet apart from centre to centre and 20 feet wide. This will mean preserving 

 20 per cent, of sissoo in the crop in addition to any found scattered over the 

 rest of the coupe. As regards trees other than sissoo, of those at present found

aroorea and possibly some species of Eucalyptus 

 are likely to prove satisfactory substitutes for sissoo as standards. 



Very little can be said on the cultivation of the trees named except 

 Eucalyptus. The species of Eucalyptus known to do well in Changa Manga as 

 proved by specimens cultivated for a sufficient length of time to show their 

 growth and also to flower and reveal their identity are : 



Eucalyptus teretioornis This is the fastest and straightest grower. 

 The wood requires to be sawn up green rejecting the core of the 

 logs, otherwise it splits very badly. Even with these precau- 

 tions there is likely to be considerable waste. 



Euca'yptns rostrata. Similar in a'most all respects to E. tereticornis, 

 but not so straight in growth. 



Eucalyptus siderophloia, Eucalyptus crebra, Eucalyptus paniculata. 

 All three are valuable timbers in Australia and grow well in 

 Changa Manga. Eucalyptus paniculata is probably the most 

 promising. All three are slow in growth compared with 

 Eucalyptus rostrata. 



Eucalyptus melanophloia. Is apt to be straggly for the first year or 

 two but soon straightens and grows well. Nothing is known 

 as to the quality of the timber, but it appears to be hard and 

 durable. 



JE/ucalyptus citriodora. Grows well in Ohanga Manga and forms a 

 very straight clean bole. Not a promising tree for cultivation 

 on a large scale as seedlings are more difficult to grow than 

 many other kinds of Eucalyptus and the diameter growth is 

 poor. 



Very many other kinds of Eucalyptus have been tried especially during 

 the last few years, but at present the only one which seems to be as good as 

 most of the species mentioned is Eucalyptus saligna. Of the species tried this 

 is the only one which approaches Eucalyptus tereticornis and Eucalyptus 

 rostrata in rapidity of growth. Many other species doubtless can be grown, but 

 under Changa Manga conditions rapidity of growth is the first consideration 

 and provided the timber produced is fairly good the fastest grower will probably 

 pay best. 



One experiment has been tried with the object of introducing 

 Eucalyptus standards in compartment 60. In the autumn of 1912 Eucalyptus 

 seed was sown as soon as the monsoon was over, that is about the middle of
