226 Memorial of George Brotvn Goode. 



6. In large halls a system of alcoves with liberal aisles, or a double, 

 triple, or quadruple system of circulation aisles, may be used to advantage. 



7. Transverse aisles are usually objectionable; when used a wdde, open 

 area near the center of the hall is advantageous. This may be enlarged 

 so as to surround some striking and symmetrical pedestal exhibit. (A 

 formal case should never interrupt the course of an aisle. ) Very wide 

 aisles may often be advantageously divided by symmetrical and graceful 

 pedestal exhibits, by which the current of visitors is parted. 



8. Objects too large to take their proper place in the cases may be 

 declared "out of classification," and used decoratively on the walls or 

 pedestals, with cross-reference labels. 



9. A small label, map, or diagram at the eye level is as conspicuous as 

 an immense one hung high on the walls. Such accessories should only 

 be made large when needed for decorative uses and treated in a decora- , 

 five manner. 



10. These principles apply also to exposition installation, in which, 

 however, an ' ' open system ' ' of installation is needed, with twice or thrice 

 the floor space for the same material that is required in ordinary museum 

 installation. 



C. — CASES AND THEIR ARRANGEMENT. 



1. The function of a case or pedestal is to protect the exhibit and 

 to display it to the best advantage. Its character should be deter- 

 mined not only by its intended use, but by the position in which it is to 

 stand, the form of adjacent cases, direction and amount of light, etc. 

 Cases should therefore be built only as need arises. They should be 

 planned so that they can be used with advantage in halls that have light 

 from overhead as well as from the sides. This precaution will simplify 

 the problem of lighting at night. 



2. Cases should not attract attention either by their austeritj^ of design 

 or workmanship, but should be simply appropriate and pleasing, well 

 locked, dust-tight, and nearly air-tight. The frames should be as light 

 and inconspicuous as possible. Transverse bars across an exhibited object 

 are unpardonable. Glass should be as large, clear, and good as possible, 

 for economy in glass is rarely true economy. 



3. The space above the 6-foot line is rarely of use, while for small 

 objects nothing is gained by display below a height of 30 inches. Large 

 objects may be shelved at 10 or 12 inches from the floor. Where the 

 aisles are very wide lower shelving for small objects is possible, but it is 

 more economical to shelve high, narrow the minor aisles, and use the 

 lower parts of the cases for storage closets. 



4. A S3^stem of interchangeable units in drawers and mounts, as well 

 as in cases, is of the highest importance, as facilitating the transfer of 

 cases from hall to hall and saving cost in manufacture. This should 



' include not only the exhibition cases, but those in the storage series as 

 well.
