13i4r CONGRESSIONAL PROCEEDINGS. 
The appended table (C) shows the number of feet of floor space (the average 
height being 10 feet) required for laboratories, workshops, and for the several depart- 
ments. This is in addition to storage space under the cases in the exhibition halls, 
and a considerable portion may be in cellars and attics. ° 
In summarizing what has just been said, it may be stated in general terms that the © 
amount of space already required for exhibition purposes alone, being (Table B) 
207,500 feet as against 100,675 now occupied, and this being exclusive of the (Table C) 
108,900 square feet needed for other objects, the accumulations have now reached 
such a point of congestion that the actual space needs to be doubled, even independ- 
ently of future increase; and I beg to repeat that, unless more space is provided, the _ 
development of the Government collection, which is already partly arrested, will be 
almost completely stopped. ; '
