Some discussion having recently taken place as to the value of New

Zealand coal as a fuel, the following results of a somewhat full

analysis may be worthy of being placed on record.

The sample to which the results refer consisted of large brownish

black lumps, many of which showed woody structure; the fractures were

conchyloid, the surface shiny and highly reflecting. It was interspersed

with a considerable amount of an amber colored resin. When powdered it

appeared chocolate brown. It burned readily, the flame being bright and

very smoky. Its ash was light and reddish brown.
