(vit) Treated ‘ Hollock ’ sleepers. 
Terminalia myriocarpa. ‘ Hollock ’ sleepers were treated under 
pressure and laid in tke Assam-Bengal Eailway over five years ago. 
Like ‘ Sain ’ it is a hard timber, though not very easy to treat, on the 
other hand the sleepers are behaving remarkably well, 85 per cent, being 
still in the first class and 8 per cent, in the second and none in ‘ C ’ class. 
Those rejected amounting to 6 per cent, and were taken out of the line 
for mechanical defects. There appears to be every likelihood of 
‘ Hollock ’ when treated, proving a very useful sleeper wood. 
{viii) Treated ‘ Sida ’ sleepers. 
Lagerstroemia parviflora. It is not known how long an untreated 
‘ Sida ’ sleeper will last, but probably not more than 2 or 3 years. Those 
treated under pressure with Assam Earth Oil and Green Oil have been 
a little over 5 years in the line, and are doing fairly well. They are, 
however, not very satisfactory as this class of timber is very liable to 
split. 
(ix) Treated ‘ Sam ’ sleepers. 
Artocarpus Chaplasha. ‘ Sam ’ was treated in the same way 
as ‘ Hollock ’ and laid down at the same time. The experimental 
sleepers are doing well, 88 per cent, being still in the first class. 
They, like ‘ Hollock,’ may prove to be a useful treated sleeper. 
(*) Treated ‘ Jutili ’ sleepers. 
Altingia excelsa. The ‘ Jutili ’ sleepers were treated in the same 
way as ‘ Hollock,’ and laid down from four to five years ago in the 
Assam-Bengal Railway. Of these experimental sleepers 89 per cent, are 
still in Class ‘ A ’ and are doing well. 
{xi) Treated ‘ Gohari Sapa ’ sleepers. 
Magnolia Sp. A few ‘ Gohari Sapa ’ sleepers were treated in the 
same way as ‘ Hollock ’ of which 85 per cent, are still in Class ‘ A,’ and 
are therefore doing well. 
{xii) Treated ‘ Ping ’ sleepers. 
Cynometra polyandra. ‘ Ping ’ wood is very liable to split, but is 
hard and well suited for sleepers, it is also plentiful. A few treated 
sleepers were laid down in continuation of the above, of which 78 per 
cent, are in Class ‘ A ’ after over five years. If this timber proves suitable 
it will help to solve the sleeper problem in Assam, as the timber is little 
used in that province.
