MARINE AQUARIA 

then be covered with a considerable quantity of moist weeds. Some of the 
fishes and other forms will survive for hours, if carefully packed as 
suggested. The illustration, Fig. 237, 1s the Buckland collecting 
can, which has a perforated false bottom connected by a pipe, pet-cock 
and hose, D. and B., with the air bulb, A. The funnel C. aids in 
aerating and siphoning the water. This may be set under the car seat 
and the bulb operated with the foot. Modifications of this device are 
easily made, and are in general use. 
Recetvinc Consignments. Upon arrival, a number of shallow 
receptacles filled with seawater should be at hand, to separate the animals 
and to quarantine them until assured that they are in healthy condition. 
The marine plants also should be cleaned with saltwater and quarantined 
a day or two before introduction into the established aquarium. ‘The 
anemones may not at once adhere in the desired positions, may attach 
themselves to the glass or roll on the bottom; or they may, by expanding 
their discs on the surface, float about for days in reversed position. Pour- 
ing water into the hollow depression of the disc will cause them to sink, 
as they then lose their buoyancy. It will be found that most of them will 
expand more freely on bright days, though some forms, which prefer dark- 
ness, will seek these localities, when offered. When considerably fed they 
will not open for some days, but if it is desired to have them do this, a 
very small particle of food given an hour before will excite the appetite 
and cause them to open very widely in expectation of a further meal. 
Aquarium Toots. These should consist of straight and bent dip- 
ping tubes, a siphoning tube and hose, a shallow net with a straight front, 
a sponge or piece of felt on a stick to clean the glass, a glass syringe for 
aeration and feeding the mussels and other low forms; a filter, as already 
described, long scissors, tweezers and feeding sticks. Pieces of charcoal 
behind and under the rockwork will serve as antiseptics and aid in keeping 
the water clear. With larger aquaria some efficient method of aeration 1s 
imperatively necessary.
