6 MISSOURI BOTANICAL GARDEN BULLETIN 
In recognition of what may now be seen and learned at 
the Garden and the appreciation of the public of the Sun- 
day opening the Board of Trustees voted to extend this 
privilege to every Sunday in the year, and the Garden is 
now open, with the exception of New Year’s Day, Fourth of 
July, Labor Day, and Christmas, from eight o’clock to one- 
half hour after sunset on week days, and on every Sunday 
afternoon. 
NEW PLANT RANGE 
The new plant range, now practically completed, repre- 
sents fourteen distinct units designed for as many or more | 
different uses, and is unique in many respects. The plans 
Were prepared by the Pierson U-Bar Co. of New York after 
sketches submitted by the Garden; the superstructure was 
built by the Lord & Burnham Co. of C icago; and the 
foundations, walls, and all other work of every kind was 
done by the Garden. Great care has been taken to provide 
the best possible conditions, such as heat, ventilation, moist- 
ure, sunlight, etc., for the particular kinds of plants which 
are to be grown in the several houses. Indeed, the plan of 
the range is primarily based on the character of the plants 
to be grown therein; that is, utility has been the first con- 
sideration rather than an attempt to produce a pleasing 
architectural effect. Nevertheless, the range is one which 
immediately excites admiration because of its beautiful lines 
and simplicity of structure, 
The approximate sizes of the houses and the uses to which 
they are to be put are as follows: 
Floral display house, 50 x 190 x 40 feet high; varied in- 
dustries house, 25 x 166 x 25 feet high; aroid house, of the 
same size as the varied industries house, with the addition 
of four display alcoves 20x7 feet; bromeliad house, 70x 
30x 18 feet high; ericaceous house, 70x 30x18 feet high ; 
two pit houses, each 58 x 20x 121% feet hi ; Six growing 
houses of the same size as the pit houses; one passage house, 
12x104x10% feet high. In addition there has been con- 
structed a concrete workroom, 100 x 13 x 10 feet high, which 
provides for a valve chamber as well as a store-room. The 
combined area of the various houses is slightly more than 
uarters of an acre and represents about 60,000 square 
feet of glass. All of the greenhouses are built on the well- 
known curved-eave plan, with iron frames throughout, and 
having, even in the larger houses, the plain flat rafter. By 
this means, the heavy girders that are such a detriment to 
the re tgs of show houses have been eliminated. More 
than the usual amount of ventilation has been provid 
?
