"Shipping Port," as the village below the rapids or falls of the Ohio was then called, was joined to Louisville by the Louisville and Portland Canal, a channel two and one-half miles long, in 1830, two years after the city received its charter. The "Louisville" or "Portland" cement, a name now applied to the product of a considerable district, was first manufactured at Shipping Port, in 1829, for the construction of this canal.
