Although there may be some practical reasons lor tearing down the structure surrounding the clock tower,' urge the committee to consider the historical importance of Old Main and opiior renovalion of

the original structure I think we all agree that the brick structure is quite beautiful and basically sound

Only a few minor repairs would be necessary 10 preserve it The cost of new electrical and plumbing systems for lhe old struclure would be less than the cos! 01 a new building with the same systems And

if a new building were to be erected, the clock tower would seem out 01 place somehow

most of the modem continent 01 Asia and Europe was south of the AsIan legion Instead 01 north as It Is

now So AsIa and Europe were connected to the west wilh what Is now North AmerIca Atrica and the Arabian Peninsula were positioned south 01 Europe with South America to the west India to the east, and Antarctica and Auslfalia south and southeast Then, aboUt 200 million yeara ago, this super conlinent began to separate into a northern continent and a SOUIhem continent The northem continent was made

of what is currently North America, Greenland, Europe, and AsIa, and the southern continent Included Antarctica, Auslralla, India, and South America By 135 million years ago, the two continents had moved

into positions that began to resemble the map that we see today, with seven continents

According to the theory 01 plate tectonics, the outer layer 01 the Earth Is made up 01 plates that are

am-tinually moving, and consequently, changing the relative position 01 the land and oceans Building on

this theory, scientists have proposed that about 250 million years ago, there was only one landmass, a

huge continent thai they have named Pangea, and It Inctuded all of the continents that we observe

today But about 200 million yean; ago the plates caused Pangea to drift and break into a Northem

continent that Included North America, Greenland, Asia, and Europe, and I Southem continent that

contained South America, India, Antarctica, and Australia By about 135 million years ago, the ptates

had separated the landmasses Into more or less the seven continents that we recognize today and

positioned them lairly close to their current locations
