DESCRIPTION:Lyman-Break Galaxies (LBGs) are the largest population of high
 -redshift (z>3) star forming galaxies and as such provide valuable insight
 s into the mass assembly of normal galaxies during the first few Gyr of th
 e Universe.  They have moderate star formation rates (~10s-100s Msun/yr) a
 nd they have ~10-100x higher space densities than the more extreme submill
 imetre galaxy population\, thus they should comprise a significant portion
  of the far-infrared background at high redshift.  But determining their t
 rue contribution to the far-infrared background has been difficult due to 
 the rather large uncertainties that go hand-in-hand with deriving dust cor
 rected UV luminosities and star formation rates.  The only reliable way of
  measuring the dust content of LBGs is directly through submillimetre obse
 rvations\, which has had a very patchy record at best\, making it difficul
 t to say anything conclusive\, until now.  In this talk I will present som
 e new results using some of the best submm data around from the SCUBA2 Cos
 mology Legacy Survey.\n
