THE WOKDERS OF THE SHORE. 157 



the vase in the sun for a lew weeks, it would 

 become a mere brine-pan. 



But how will you move your treasures up to 

 town ? 



The simplest plan which I have found success- 

 ful is an earthen jar. You may buy them with 

 a cover which screws on with two iron clasps. If 

 you do not find such, a piece of oilskin tied over 

 the mouth is enough. But do not fill the jar full 

 of water ; leave about a quarter of the contents 

 in empty air, which the water may absorb, and so 

 keep itself fresh. And any pieces of stone, or 

 oysters, Avhich you send up, hang by a string from 

 the mouth, that they may not hurt tender animals 

 by rolling about the bottom. "With these simple 

 precautions, anything which you are likely to find 

 will well endure forty-eight hours of travel. 



"What if the water fails after all ? 



Then Mr. Gossc's artificial sea-water will form 

 a perfect substitute. You may buy the rc(iuisitc 

 salts (for there are more salts than " salt " in sea- 

 water) from any chemist to whom ]\Ir. Gossc has 

 intrusted his discovery, and, according (o his di- 

 rections, make sea-water fi)r yourself.* 



* Mr. W. r.olfon, Chemist, yf HO Ilulboni Bnm, London, 

 will furnish the materials.
