and we determined, at the first opportunity, to arrange our collections in 

 the same manner. 



The very small, minute species were exhibited in little bottles or 

 vials, in which was placed a number corresponding to that on the label. 

 This was a very necessary precaution, the Professor told us, to guard 

 against the contents of the trays being spilled, and so mixing up 

 the collection. 



Before we left the Professor's house for our homes he asked us where 

 we expected to spend our vacations. We told him that we had planned 

 to spend a few weeks together on the seashore, and that we would be in 

 Providence, Rhode Island, about the middle of July. He made us very 

 happy when he said that he also expected to visit the coast during the 

 summer, and would be in Providence about the time that we were to be 

 there. He added that he would be pleased to plan some collecting trips 

 with us to obtain marine shells and clams, so that we might compare them 

 with their fresh-water relatives which we had already studied. We bade 

 him good night, and returned to our homes, our hearts stirred with the 

 anticipation of a few weeks to be spent on the seashore in company with 

 our friend and instructor.
