We present the millimeter continuum and molecular line observations of the middle condensation of the L1617 cloud. Various molecular structures were found in the HCO+ and the HCN lines. The driving source of the HH 270 flow was detected in the continuum and is surrounded by a flattened dense molecular core with possible infall motion. The HCO+ and the HCN emission at the ambient cloud velocity are enhanced along the HH 270 jet axis, but the molecular clumps do not show a kinematic sign of outflow. The enhancement could be caused by irradiation from shocks. In the immediate vicinity of HH 110A, the northernmost knot of HH 110, neither a continuum source nor any evidence of jet-cloud collision was found. To the west of HH 110, there is a filamentary structure of dense gas that contains at least two outflow sources. The driving source of the IRS 2 jet was detected in the continuum.
