Narrative:

Departed bos runway 22R. Within 1 min of takeoff a 'smoke cargo' warning presented. Warning ceased, then returned within 30 seconds. First officer directed to assume radio control. Captain performed checklist for smoke cargo warning. Emergency declared. ATC vectored for immediate return to land on runway 27. Communicated with flight attendant to brief the circumstance and to verify status of cabin. No smoke, flame, or odor reported. Uneventful, but overweight landing performed by first officer. Aircraft taxied off landing runway onto taxiway west. Evacuate/evacuation initiated utilizing main (forward) cabin door only. Passenger were directed to congregate forward and upwind of aircraft. Crash fire rescue equipment was informed of presence of halon vapor in cargo compartment. Evacuate/evacuation was orderly with no adverse circumstances or injuries noted. Aircraft was secured. First officer performed flawlessly, a strong asset to the successful outcome of the emergency. Flight attendant performed ideally, remained calm and helped the passenger remain calm. ATC (departure, tower then ground) provided rapid, accurate help, another strong asset. Crash fire rescue equipment was waiting for us. Met aircraft as we stopped and assisted with evacuate/evacuation.
