In the autumn, leaks in the steam main from power house 
no. 1 to the museum building developed when steam was 
turned on and it was found necessary to replace portions 
of this pipe with new lengths and to tighten up the joints 
of others; this required considerable earth excavation, as 
the trench in which these pipes rest along this line is too 
small to permit work to be done within it. Steam leaks 
also developed at several points within the museum building 
and were repaired. 
Leaks in the roof of the museum building, which have 
been a more or less continuous source of annoyance, were 
repaired, and portions of the walls of this building and of 
the retaining walls of its front approach were pointed. It 
will be necessary soon to go over a large portion of the 
cornices of the museum building and other parts of its 
Part of the wooden floor of the stable showed weakness 
during the spring and was found to be partly decayed; it 
was replaced by a concrete floor. It will be well to treat 
other parts of this flooring in the same way when the 
necessity arises. 
The minor buildings have required little attention and 
are in good condition, and the same is true of the whole of 
conservatory range no. 2. 
The necessity of a shop for mechanics mentioned in my 
last annual report is becoming more and more apparent, 
and application for an appropriation for such a structure 
has been included in the estimates of construction require- 
ments during the next five years, requested by the Finance 
Department of the city. 
A hexagonal concrete pergola at the herbaceous grounds 
may be built during the coming year, plans for it having 
been approved by the Municipal Art Commission and an 
appropriation of $2,500 voted for it by the Board of 
Estimate and Apportionment.
