L = Lowrie text; CH = Cox and Hart text;

*.pdf are Acrobat files accessible over the net by clicking on the link;
*.ppt are Powerpoint files;

Both types of files can be downloaded or taken form our class folder in the computer lab (2161 Snee):
Z:\class\Class_geo388\pwrpt_files\

The Powerpoint material appears as a slide show - use the right or left arrows to move forward or backwards. Alternatively, you can right click on the link (either *.pdf or *.ppt file) and download the file for more detailed examination. To download files from our class WWW site, you will need to give a User Name and a Password, which I will email to you.
