These words were penned just hours before the doomed liner struck an iceberg and sank.
Written on Titanic-headed notepaper, the letter was written by Esther Hart, a passenger enjoying the early uneventful days of the Titanic's maiden voyage, accompanied by her husband and daughter.
Esther writes: "The sailors say we have had a wonderful passage up to now. There has been no tempest. It is very nice weather but awfully windy and cold".
The Hart family were planning to emigrate to Winnipeg, Canada, where they were going to run a chemists.

Esther and her daughter survived the sinking of the Titanic, however, her husband Benjamin perished with over 1,500 other passengers in the Atlantic Ocean.
After the Titanic struck the iceberg in the north Atlantic, Benjamin Hart, a second class passenger, woke Esther and Eva and guided them to a lifeboat.
He told his wife to hold 'mummy's hand and be a good girl' and that he would see them soon. His body, if recovered, was never identified.
The letter was found in the pocket of Benjamin's sheepskin coat which he gave to his wife to keep warm.
When Esther arrived in New York with Eva she sent a cable to her parents to confirm they were safe but her husband was missing.
Eva Hart became one of the most well-known survivors of Titanic, mainly because of her outspoken criticism of White Star Line for failing to provide enough lifeboats.
