University Past Time

Dr. Tom Gorham is a professor at Central States University located on the Mississippi River below St. Louis. One of his assignments is to secure funding for research projects in the College of Science and Engineering.
Dr. John "Raj" Jhangi, a Professor of Physics, tries an experiment with an experimental powerful electromagnet with results that open a new realm in Physics. Tom's job is to coordinate the efforts to solve the dilemma of the experiment. The Navy Department lends an old escort destroyer to the University to supply added D.C. power to expand the experiment while the Pentagon tries to obtain control over the experiment as a defense project. One of their observers, an officious naval captain, interferes with the experiment and causes the experiment to blow up, sending a portion of the University back in time. Efforts to return only puts the group further into the past and the people and a portion of the university winds up in the year 1003 A.D.

The colony meets the Cahokian Indians and establish a common ground of support for each other when the colonists defeat a warring Indian tribe who attack the Cahokians. Further complications arise when the Indians desire to become "one people" which requires the council members to take an Indian "princess" and some women to marry an Indian "prince." This is done to make "One People" and thus seal the pact.
The people struggle to survive; scrounging seeds, food and clothing from various sources and
