Screen Cover See: Keep no more than 2-3 scorpions together at a time. Watch to see if they fight. Sometimes they destroy each other. As they need con¬ditions typical of natural habitat, establish desert habitat in large vivarium with screen cover see cover (see Part II). Cover bottom with thick layer of loose sand; top with inch of fine sand mixed with some soil.
Use 5- to lo-gallon aquarium with tightly fitting screen cover see top, which must be escape-proof. As roaches breed in dark quarters, cover bot¬tom with 2 inches of sawdust. Provide plenty of cover material; scat¬ter many thin pieces of bark over sawdust; pile several over each other. Warmth is essential for normal development; place aquarium where temperature is most constant; put near Heater during night.See Also Cover Bottom:One or two crayfish may be housed together; if more than one, watch carefully at first; they may fight when maintained in close quarters. Use 5- to 10-gallon aquarium. Cover bottom with 2 inches of sand and pebbles; try to reproduce stream bottom from which creature was taken. Add enough stream water to more than cover specimen. Place fairly large, flat rock in habitat so that it extends above water surface, permitting crayfish to climb out of water at will.
Use "rat apartment" cage, which is large enough and so constructed as to facilitate cleaning (see Part IV). Cover bottom with 2 inches of sawdust-shavings mixture or any commercial cover such as pitch pine shavings, so as to counteract odor. Place cage where sleeping box is out of drafts.
On The Other Hand See Pos¬sible To Cover:A better way of operating, to get as many weddings as pos¬sible to cover and to get the most profit from each, is to offer to cover the wedding without any shooting fee and to charge only for the prints which you deliver after the customer has seen a set of proofs and has made his choice of pictures. Such an offer is particularly appropriate for the beginner who has no reputation with which to impress the prospect and who is eager to do as much shooting as possible to gain experience and reputation.
Sometimes the signature of the artist was inscribed directly on the plate, or the name of the studio appears inside the case cover, but by far the majority of portraits bear no indication of producer. For the most part da¬guerreotypes reflect the style of a period, rather than of an individual, and personal attribution becomes impos¬sible in the absence of documentation. Hundreds of da- j guerreotypists are known by name, and thousands of i daguerreotypes exist, but it is only rarely that the docu- I mented oeuvre of an individual artist can be studied.
