OF the city With this idea in mind. TRIBUNE
reporter called at the Board Of Public Works ycB-
ter1ay afternoon, and had conversation with
City Engineer CheBbrough upon the condition Of
the watcr-mains Of the city, quite largo num-
her Of which common report had set down quite
frequently of late ~ frozen up aud ready at tue
return Of warm weather to scoop ho!es In the
ground In their vicinity. The following conver-
satton between tho Engineer and reporter ahowH
that the state Of affairs Ia
not NEARLY go FAD
"a had been reported.
lteportor- hear, Mr. Chesbroush, that quite
a number Of tho water-mans Are frozen, and
tbht considerable trouble will result tLerefrom in
the Bpring time. ...-
sir. Choabrough-I cannot find out that many
arc frozen, aud where tlos arc 1t ia At What arc
called "dead ends." This is = plece OF pipo
which, terminating abruptly, IL not OF course,
lion. Tho watef in these being motlonfeas. it
freezes up more easily. These '.dead cllds ARE
chiefly on the North and South Sides. You aeo
wo don't carry tho watcr-pipes further than they
pay. aud as there good many iaolated houses III
thoao divisions, thore are consequently good
many dcad ends. l do not believe that there Ii
watet-main frozen In the South or Weas DiyB-
ions north Of Twelfth sttoet
Neposter-How many, 81 these "dead ends
arc frozen to your knowle1ge?
Mfr. Chesbfough--l have not beard Of over
l,alf-a-dozen, and they are the only frcezy
cases know Of, expect somo cnses, however,
in localities where, though the mainH were in
circuit there arc very few houses to draw watar
from tho main, as here the circulation would
hardly be much greater th.n at "dead snd."
HOW Do You KHow2

aIr Chesbrough-We havo q regular army Of
