We mosaicked a field containing $\\sim 225$ optical or near-IR-identified young stars, $\\sim 60$ of which are also optically-identified \"proplyds\". We detect continuum emission at 850 $\\mu$m towards $\\sim 80$% of the proplyd sample, and $\\sim 50$% of the larger sample of previously-identified cluster members. Detected objects have fluxes of $\\sim 0.5$-80 mJy.
