baroques are found near the hinge of the 

 shell and are usually long and pointed at one 

 end. Slugs grow in or near the muscles 

 which serve to draw the two valves of the 

 shell together. They are always irregular, 

 generally lack lustre and are therefore of 

 little value. 



Color and Lustre 



Pearls are of as many tints as flowers, 

 birds or butterflies and, while as a rule, 

 they partake of the color of the lining of 

 the shells from which they come, this is 

 by no means always the case, as a white 

 and a colored pearl may be found growing 

 in the same shell, side hy side. The tints 

 and shades seem almost endless but it would 

 indeed be diflicult to say which color makes 

 the most beautiful pearl. Some of the 

 pearls found in Wisconsin are of such extra- 

 ordinary color and lustre as to cause one 

 to doubt, at first glance, their being pearls 

 at all. Some resemble drops of liquid gold 

 or copper, others are of an intense peacock 

 green or blue while still others are a most 

 exquisite rose pink or lavender. Blue- 

 black, dark purple or dark green and purple
