In this artefact we can contextualize the thinking for people in charge of the surveying and clearing of obstacles. Within the first paragraphs, we can see the author is mentioning that a person named Mr. Dewdney had failed to consider the landscape and geography of a location that railroad tracks would be passing through. There are many different contexts that this sentence could be referring to, but based on the next paragraph, it may be safe to assume that it is a monetary or tourist concern. The concern being that since the last time Mr. Dewdney has surveyed the Bute Inlet line area, some kind of areal change as happened, such as a fire or deforestation. Shortly after we see the discussion of sale of lumber of the trees cut down if the railroad were to be put in the Fraser Valley area, and how the area would be an option for agriculture if they did. The author also continues by listing the industry towns, such as coal or iron, and how the demand will increase, and how the railroad will help supply.
