Then the work of manufacturing arms and ammunition , in anticipation of another midnight invasion , began . Before the `` preparedness program '' of the afternoon was started , Miss Ladd addressed the group of Camp Fire Girls thus , speaking in low tone , of course , in order that she might not be overheard by any eavesdropper who might be in hiding in the vicinity : `` Now , we want to do this thing right .
