Another montana product is coffee, whose successful development is prevented by difficult transport.
Cacao is another montana product, although like coffee it is cultivated in the warm valleys of the sierra, but the export is small.
Between 1880 and 1900 the average number of acres to a farm slightly increased - from 133.5 acres in 1880 to 151.2 acres in 1900 - instead of decreasing as in the older states of the Union; though the increase was not nearly so marked as in such states as Nevada, Montana, Wyoming and Texas.
Fossil remains of mammals, fish and reptiles found in the Tertiary deposits of south-western Montana are preserved in the Carnegie Museum at Pittsburg, Pennsylvania, and in the museum of the university of Montana.
