“That，” said Doctor Cornelius， “is the greatest and most sacred treasure of Narnia. Many terrors I endured， many spells did I utter， to find it， when I was still young. It is the magic horn of Queen Susan herself which she left behind her when she vanished from Narnia at the end of the Golden Age. It is said that whoever blows it shall have strange help.no one can say how strange. It may have the power to call Queen Lucy and King Edmund and Queen Susan and High King Peter back from the past， and they will set all to rights. It may be that it will call up Asian himself. Take it， King Caspian： but do not use it except at your greatest need. And now， haste， haste， haste. The little door at the very bottom of the Tower， the door into the garden， is unlocked. There we must part.”
“Can I get my horse Destrier？” said Caspian.
“He is already saddled and waiting for you just at the corner of the orchard.”
