How can readers know that the book is placed in the Victorian Era?

Readers can know that the book is placed in the Victorian Era because of courtship and marriage relationships, the school system, and the transportation.  The marriages and dating relationships of this time period were based off of money and social connections. Marriages were more business contracts than love. (http://www.angelpig.net/victorian/engagement.html) The school system shows readers its the Victorian Age because most kids went to boarding schools or had governesses. Adele has a governess and Jane attended Lowood, a boarding school. Most of the upper class were either tutored by governesses or went to boarding schools. Now there are public schools and international schools. There is also the factor of transportation. Rochester travel either by horseback or carriage. There is talk of him taking a boat across the Atlantic. So there were no planes or trains during this time. So does the rest of the characters in the books. Readers can also tell its the Victorian age because of the characters talk and knowledge. Rochester and others refer to America and the Carribean as the "West Indies". This was what they referred to America when Christopher Columbus first sailed to America. These are some examples of many that show readers how they know it is in the Victorian Era.
