What is the name of the children's book about a family who lived on a junket?

A Junket is a trip or excursion,not a vessel. I think you might be thinking of- Five Little Starrs on the Canal Zone, written sometime in the twenties. Now why do yoiu suppose Daddy has that heavy Russian hat? I never read this book but heard it was quite popular in the twenties and the details on the Canal Zone are accurate. they Familky had Four Girls and one Guy...Begin to get the idea... By the way the principal Engineer of the Project-Gen. Goethals conceded- the Impossible jobs always take Longer! One wonders.. it"s fiction of course, but can you imagine the Romanovs on a beat up live-in Barge on the Canal Zone?
