There are not many spectacles more interesting to the miner, than that termed a "rush" to a gold-field newly discovered, and reported to be "rich." The scene is one of the greatest excitement. On the ground to which the "rush" is directed, all the vices and amusements to be met with in large cities, soon make their appearance. Where, perhaps, a month before, not a human being could have been seen, taverns, with magnificent interior decorations, billiard-rooms, bowling-alleys, rifle-galleries, theatres, and dancing-saloons, will be erected; in short, a city, where, but a few weeks ago, there was nothing but the "howling" wilderness! On my arrival at the Avoca diggings, I marked out a "claim," and for several days my occupation was that of "shepherding" it. To "shepherd a claim," is to keep possession of, and merely retain it-- until, by the working of other claims near, a tolerably correct opinion may be formed: as to whether yours will be worth digging or not. The system of shepherding claims, is only practised where the gold lies some distance below the surface; and where the claim can only be prospected at the expense of some money and trouble. The claim I had marked out, was a large one--larger in extent than one person was entitled to hold. For this reason, on the third day, after I had taken possession of it, another man bespoke a share in it along with me. I did not like the look of this man; and would have objected to working with him; but he would not consent to divide the ground; and the only way I could get clear of him was, to yield up the claim altogether. This I did not wish to do: for it stood, or rather "lay," in a good position for being "on the lead." I have said that I did not like the look of the intruder. This dislike to him arose, from the circumstance of his having a strong "Vandemonian expression" of countenance; and I had a great prejudice against those who, in the colonies, are called "old lags." We "shepherded" the claim together for a few days, when the prospect of its being on the lead, became so fair, that we at length commenced sinking a shaft. The more I saw of my companion, while we were toiling together, the weaker grew my aversion to him; until, at length, I began to entertain for him a certain feeling of respect. This increased, as we became better acquainted. I learnt that he was not from Tasmania, but from New South Wales; and my prejudice against the "Sydneyites" was even stronger (having been formed in California,) than against the "old hands" from Van Dieman's Land. The "Vandemonians," generally speaking, have some good traits about them, that are seldom met amongst those from the "Sydney side." The convicts from the former place, have more generosity in their wickedness, less disposition to turn approvers on their companions in crime, while at the same time, they display more manliness and daring in their misdeeds, than do the "Sydney birds."
