Uncle Hammer is very much adored by the Logan children.
             'We swayed with excitement, then as if by signal we both cried "Uncle Hammer!" and dashed into his arms.'
             He spends Christmas season with the Logan's and brings gifts for the children. They always look forward to him coming as we see from the way they act around him.
             He is big ma oldest unmarried son, who lives up North and earns a good living, though we are not told what he does. We know he is quite wealthy as he can afford to buy nice things for the children and also owns a Packard, like Mr Grangers but only a few months newer.
             "Like papa, he had dark, red-brown skin, a square-jawed face, and high cheekbones; yet there was a great difference between them somehow. His eyes, which showed great warmth as he hugged and kissed us now, often had a cold, distance glaze, and there was an aloofness in him which the boys and I could never bridge."
             From this quote we learn that he is very good-looking man and that he shows affection towards the children from the way he kisses and hugs them. He is also very kind to them but even they notice that there is something about him, which makes him very different from their own father. He seems to be very independent and keeps to himself. This could be one of the reasons why he doesn't have a wife and children of his own.
             He is very much a family man, like his brother papa Logan as he was very annoyed and hurt at what Mr Simms had done to Cassie but unlike Papa, he doesn't think it through to come up with a more educated plan. Instead he prefers to act then and there and heads out into the night with his shotgun to seek revenge. We also see that he is devoted to his family when he sells his car to help protect the land. He burrows his temper in order to protect them as he knows his actions could harm them as well as himself. His only resistance is the well being of his family...
