The estimate is a minimum one compared with prices in other 
places. The materials being so convenient a large saving, com- 
paratively considered, might be effected. It should, however, be 
understood that in districts where there are no such materials at 
hand and where long carriage would be necessary, the cost would 
be accordingly much larger. The progress would be for one 
steam crusher “)'=25 days, or roundly speaking one mile per 
month, which would give a day or two for repairs and removal. 
Even with this expenditure we must not consider we would 
have perfect roads without much attention to repairs. The 
weather in Nova Scotia will act to some degree on the materials. 
Frost expands the moisture in the crust, and when the thaw 
comes a general disintegration will take place. Rain following 
frost and thaw is very damaging, and alternations of these 
without repairs and attention would soon destroy the best 
Macadam road coverings. The extent to which these various. 
effects may be injurious will depend on the nature of the road 
materials, on the drainage, subsoil, situation, and many other 
accidental circumstances. 
There is a general wish for steam stone crushers and for 
Macadain roads throughout the Province. The author would 
recommend that the Government introduce them into such mun- 
icipalities as would be most likely to ensure their successful 
operation, where the material is plentiful and possibilities of 
success most promising.
