"The country has been of better character since leaving the Buttes than E. of them, but has now a very fertile appearance. This may be said to begin about the 3rd crossing of Milk R of the line"

The quote from George Mercer Dawson offers interesting insights into his observations of the landscape throughout his expeditions. Dawson was a popular Canadian geologist and surveyor in the late 19th century, and his writings typically supply comprehensive descriptions of the natural environment.

In this passage, Dawson assesses the changes in the landscape and its viewed quality as they moved away from the Buttes, which are most likely small, separated hills or mountains in the topography they were surveying. The expression "better character" suggests an improvement in the general environment or surface after leaving the Buttes. This might suggest that the land became more navigable, aesthetically appealing, or maybe better for particular usages such as agriculture or settlement.

The expression "than E. of them" suggests that Dawson is comparing the western side of the Buttes to the eastern side, suggesting that the land to the west is more suitable. This could be due to a range of elements such as more fertile soil, much better vegetation, enhanced water accessibility, or merely a more enjoyable landscape.

He then keeps in mind that the nation now has a "very fertile look." This observation signifies that Dawson sees pledge in the land's ability to support agriculture or sustain plant life, which typically associates with a richness in resources such as water and nutrient-rich soil. This modification in the land's fertility may be especially noticeable after crossing the Milk River, which is pointed out as a substantial marker in the journey.

The recommendation to the "3rd crossing of Milk R" suggests that this river was a repeating landmark in Dawson's journeys and mapping efforts. Rivers are vital in forming the fertility of the surrounding land as they offer important water resources and contribute to the community's total health. The Milk River crossing, for that reason, marks not just a geographical point but also a transition to a more fertile and promising landscape.

In summary, Dawson's reflections highlight a journey through diverse terrains, keeping in mind how specific geographical functions influence the land's character and possible uses. His mindful observations were essential to mapping the large Canadian landscapes and understanding their capacity to support settlement and development.
