Connor gave her a reassuring smile, and with Jacob distracted by her singing, he snuck out the stable. He ran across the field, towards the house, going straight for his book shelf, and beginning to flip quickly through books. 

He tried to be as fast as he could, looking for an entry he had come across ages ago, It took him longer than he wanted, and worried about Elizabeth, he ripped the page out of the book, and ran back across the ground, to the stable. Bessie was shaking in her stall,whining and shifting nervously. 

Connor moved to Elizabeth, Jacob was somewhat calmed, listening as she sang. 

Connor began to receite the Latin from the page, the ritual that would hopefully bind Jacob to an object, in this case a horse shoe that he dropped in the circle, snatching his arm back quickly. With that, he could bury it in the dirt, and trapped the ghost there. 

He read the latin flawlessly, and when it was finished, Jacob was still agitated, but as Connor broke the circle, he couldn't move from the horse shoe.
