There was a feller here once by the name of Jim Smily, in the winter of '49 - or maybe it was the spring of ' 50 - I don't recollect exactly, somehow, though what makes me think it was one or the other is because I remember the big flume wasn't finished when he first come to the camp; but anyway, he was the curiosest man about always betting on anything that turned up you ever see, if he could get anybody to bet on the other side, and if he couldn't he'd change sides - any way that suited the other man would suit him - any way just so's he got a bet, he was satisfied. But still, he was lucky - uncommon lucky; he most always come out winner. He was always ready and laying for a chance; there couldn't be no solitary thing mentioned but what that feller'd offer to bet on it - and take any side you please, as I was just telling you; if there was a horse race, you'd find him flush or you'd find him busted at the end of it; if there was a dog-fight, he'd bet on it; if there was a cat-fight, he'd bet on it; if there was a chicken-fight, he'd bet on it; why if there was two birds setting on a fence, he would bet you which one would fly first - or if there was a camp-meeting he would be there regular to bet on Parson Walker, which he judged to be the best exhorter about here, and so he was, too, and a good man; if he even see a straddle-bug start to go anywheres, he would bet you how long it would take him to get wherever he was going to, and if you took him up he would follow that straddle-bug to Mexico but what he would find out where he was bound for and how long he was on the road. Lots of the boys here has seen that Smily and can tell you about him. Why, it never made no difference to him - he would bet on anything - the dangdest feller. Parson Walker's wife laid very sick, once, for a good while, and it seemed as if they weren't going to save her; but one morning he come in and Smily asked him how she was, and he said blessing of Providence she'd that she don't, anyway.

Unit Converstions A factor is a fraction or factor written so that the denominator and numerator are equivalent values with different units. One of the most useful conversion factors allows the user to convert from the imperial system to and vice versa. Since 1 inch is exactly the same length as 2.54 cm, the factor may be expressed as: These two lengths are identical so multiplication of a given length by the conversion factor will not change the length. It will simply express it in a different unit. Now if you wish to determine how many centimetres are in a yard, you have two things to consider. First, which of the two forms of the conversion factor will allow you to the imperial unit, converting it to a metric unit?
