this knoll was necessary for landscape considerations in 
preparing the ground for the proposed new flower garden 
at conservatory range 2. It proved to contain building 
stone of a very high quality. 
Some stone for path foundations was also excavated in 
the rocky hill just north of the museum building, where 
the surface remains unfinished. 
Additional drainage was accomplished along the drive- 
way at the mallow garden by laying over 200 feet of 4-inch 
and 3-inch pipes, and a swampy area was thus reclaimed. 
Additional data may be found in the report of the Superin- 
tendent of Buildings and Grounds hereto appended. 
Water Supply 
The water pipes have not been extended during the 
season, but an extension is now necessary, owing to the 
decrease in pressure during the past several years in the 
supply of the mansion. A new connection seeking to 
improve this pressure was made a few years ago, and fora 
time appeared satisfactory, although the pressure did not 
reach much above the second floor. What is apparently 
needed is to purchase and lay about 600 feet of 4~inch water- 
main from near the school garden to the rose garden, along 
the south side of the uncompleted driveway, and connect 
this with pipes already laid reaching to the mansion. 
I have elsewhere referred to the defective water supply 
of the northern end of the herbaceous garden, which should 
be made good, and a water pipe is needed through the 
school garden. 
Buildings 
Extensive repairs were found necessary on the museum 
building, on the roof of conservatory range 1, and on the 
boilers in power house 1, requiring high expenditure for 
materials. A considerable portion of this work was made 
necessary by the arctic temperatures of the early part of 
the year, which caused a maximum amount of contraction 
in structures and the subsequent loosening; also the neces-
