on  the  previous  occasions  referred  to.  The  ladies,  many  of  whom 
were  present,  were  entertained,  as  usual,  during  the  business  sessions, 
by  euchre  parties,  carriage  drives,  guessing  contests,  bowling  con- 
tests, etc.,  and  it  was  the  opinion  of  nearly  everybody  that  the 
Association  never  had  a  more  enjoyable  or  a  more  profitable  meet- 
ing in  its  history.  The  one  disadvantage  of  the  location  was  the 
fact  that  the  hotel  is  so  near  the  railroad,  that  the  passage  of  the 
many  through  trains  made  the  efforts  of  some  of  the  speakers  fruit- 
less, and  it  was  customary,  after  the  first  day's  sessions,  to  stop  the 
proceedings  until  the  train  had  passed  by. 
Many  of  the  members  remained  at  the  hotel  for  the  balance  of 
the  week,  some  of  them  taking  side  trips,  as  to  Wilkesbarre  and 
nearby  points  of  interest,  and  it  was  very  evident  from  the  spirit 
shown  that  more  and  more  of  the  members  are  looking  forward  each 
year  to  making  this  particular  week  a  period  of  enjoyment  as  well 
as  profit.

Formula  for  Tooth-Pastes. 
By  Henry  C.  Blair. 
The  author  stated  that  the  difficulty  usually  experienced  in 
formulas  for  tooth-pastes  is  found  in  that  the  liquids  and  solids  do 
not  stay  mixed ;  that  the  glycerine  separates  on  the  top,  and  the 
sediment  goes  to  the  bottom  in  such  a  manner  that  the  preparation 
is  useless.  He  suggested  a  formula  which  had  proven  satisfactory 
in  his  hands,  and  which  was  free  from  this  objection.  The  formula 
was  as  follows : — 
Soft  soap,  made  from  cotton-seed  oil,  I  ounce  ;  glycerine,  8  ounces  ; 
starch,  y2  ounce;  water,  y2  fiuidounce ;  precipitated  carbonate  of 
calcium,  8  ounces ;  oil  of  peppermint,  y2  ounce ;  coloring  matter  as 
desired. 
A  glycerite  of  starch  is  first  made  with  the  starch,  glycerine,  and 
water ;  the  soap  is  then  added,  followed  by  the  coloring  and  flavor- 
ing ingredients,  and  a  thorough  mixture  is  made.  The  precipitated 
chalk,  which  should  be  bolted  through  a  No.  14  bolting-cloth 
sieve,  is  then  gradually  added,  and  the  whole  worked  up  into  a 
smooth  paste.  The  author  suggests  that  any  desired  flavor  may  be 
used,  and  that  carmine  coloring  seems  to  be  more  popular  than  any 
other.    If  made  in  large  quantities,  he  suggests  the  use  of  a  putty
