“Doubtless,” he agreed, also laughing. “But I shall be safe enough on my boat. I don’t intend to move her, and probably she rests on the muddy bottom of this bay and marshy land.”

The houseboat was not large. It consisted of a sort of large shed, with windows, doors, and a flat roof perched on what had once been a scow. There was a narrow space running all around the house part, between it and a low rail. There was a small float at one end to which a rowboat was made fast. From the float a cleated plank gave access to the lower deck of the boat, if a deck it could be called. There was also a short flight of rather rickety steps at the stern by which the girls had come aboard. The houseboat had once been painted green, but little of the original color remained.

“Will you follow me?” Dimitri Uzlov requested, opening a sagging door which led into the rear part of the houseboat. “This is where I do my work.”

The girls saw that the interior of the craft consisted of really but one large room, divided by heavy hanging curtains into two apartments. The one they had entered did the double duty of a sleeping and working space, for there was a cot in one corner. On a table gleamed a bright brass samovar with some dishes about it. There was an easel and on a chair near it brushes in pots, tubes of paint, and a much-smeared palette. The curtained-off part was the kitchen.

“I am finishing a marine for a client,” the artist said, indicating the half-finished canvas on the easel.

Arden and her chums noticed several canvases stacked together near one wall, and standing beside a window was another easel with a picture on it. But what the subject of this picture was could not be seen, for it was covered with a sheet.

“Oh, how lovely it is here!” Arden exclaimed. “To have a place all your own to do just as you please in and no need to worry about neighbors looking in your windows!”

“At least I am sufficiently isolated here,” the Russian agreed. “The houseboat is hard to come at. I always loved marshlands. That is one reason I was attracted to this boat, old and shabby as it is.”

“It’s wonderful, I think,” murmured Sim.

“But a little lonesome,” suggested Terry.
