A man stops at a gas station. He very quickly and anxiously tells the man who runs the station to put some gas in his car, and is asked why he is in such a hurry. He tells the station owner that he's about to dig for gold. The station owner then laughs and tells him that it's a useless idea, since there's no gold to be found, no matter where one searches. He then then begins to tell the man in the car the story of his long, troubled search for gold back in 1849, as we are shown in flashback.
Some cartoons from around this time may still be considered classics today, while others have been forgotten. Since it appears that no one else has commented on "Gold Rush Daze" on IMDb yet, it's obviously one of the more obscure ones of its time. I can understand this, as it's not very memorable, and may be a bit dated. However, I've definitely seen much worse excuses for comedy. This short does have some reasonable slapstick gags, and could be enjoyable for fans of these old cartoons, especially kids. I'm not quite sure about the availability of this Merrie Melodies piece right now, but for hardcore fans of these old animated shorts, it might be worth looking for.
