The ox warble : a $50,000,000 tune.

An amusing silent instructional film with a cartoon animated cow and accompanying theme tune about the cost of warbles to the farmer (although this film is silent). There is a short dramatic sequence; a farmer calls (picture has light scratches) and the vet uggests the 'government' man is called in. The warble fly affects milk production. The instructional element is how to squeeze the warbles out or apply a salve topically. The life cycle of the fly is described and how they infest the cattle. This is illustrated via cartoons. The poor cartoon cow gets thinner and thinner; comical captions subsequnetly appear alongside the images. Warbles particularly affect hides; hides are handled and the holes the flies have created are counted. The film suggests that the way to tackle the problem is to get the whole community involved.
