These two short tapes consist of a brief description of 50 years of white-red relations, treaties and conflicts. Because of its brevity, there is little detail presented. The text is interesting and appears to be factually correct. The presentation is relatively unbiased, and is quite interesting. It would make a good audio tape. The extra loud background music and simulated battlefield noise sometimes drowns out the text. The visual portion consists of old photographs, presumably authentic in detail and clips from old grade B movies which are quite far from authentic. These are rerun from 6 to 10 times throughout the presentation and, of course, have no bearing on the text. Except for the extreme brevity and the overwhelming background noise, one can ignore the visual effects and derive a worthwhile understanding of many aspects of the period of the Indian Wars.

It is curious that one one the more significant achievements of "Pastor" Charles Taze Russell is omitted above. That fact is that he was the primary founder of the Watchtower Bible and Tract Society, and the religion now known as "Jehovah's Witnesses." No small amount of his theology is controversial in the body of the Church as a whole, as it would be (for different reasons, perhaps) amongst Jehovah's Witnesses.

This Stainless Steel & Glass Diner Cake Set is gorgeous! If your thinking of getting it for yourself or a gift, dont hesitate, you will not be disappointed! The glass dome is heavy which is great, not flimsy thin glass at all. Looks great sitting on our buffet.
