“Why don’t we hike out there right now and invite her to our next meeting?” Sunny Davidson proposed. “Anyway, I’d like to see Windmill Farm.” “So would I,” declared Rosemary, who had heard a great deal about the nursery from her friends. “May we go right now, Miss Gordon?” “Well--I had thought we might make scrapbooks this afternoon.” “Can’t that wait?” pleaded Vevi. “It’s such a nice day for a hike.” “I think so too,” agreed Miss Mohr, supporting the girls. “Let’s all go.” Windmill Farm was only a short way into the country. The Brownie Scouts enjoyed the walk and made the most of it by noticing birds, flowers and trees as they hiked. Presently, they came within view of the Dutch windmill. However, it was such a still day that the giant arms hung motionless. Miss Gordon told the children that in Holland similar windmills were needed to pump water and prevent the sea from flooding lowlands. She explained, too, that the people of The Netherlands love flowers and are noted for raising especially fine tulips. “Our best bulbs come from there,” she declared. “Since Peter Van Der Lann started his nursery here, Rosedale is rapidly becoming a known flower center. Many folks say that his imported bulbs are the best that can be bought anywhere in this country.” “Did you ever hear of a Golden tulip?” Vevi questioned, recalling the name printed on Mr. Van Der Lann’s boat. “There are all types, Vevi. All colors too. Nurserymen constantly are trying to develop new strains.” The driveway was fringed with pink and white dogwood trees which had splattered their petals on the gravel. A big gray sedan stood in front of the little nursery office building. “Mr. Van Der Lann must have a customer,” Miss Mohr remarked. The nurseryman was talking to a well-dressed woman in a navy-blue suit and fox fur. However, when the Brownie Scouts trooped into the office, he noticed the party at once. He bowed to Miss Gordon and bestowed an especially nice smile upon Miss Mohr. “Just a moment, please,” he requested. While they waited, the Brownies wandered about the office room. Garden tools and seeds were for sale, and there were bins of bulbs and tubers. Connie and Vevi looked eagerly about for Hanny. “You should find her at the house,” Mr. Van Der Lann advised. The Brownies dashed off in search of the little Dutch girl. However, at the house, no one answered. The door to the kitchen stood ajar, but not even the housekeeper was there. “Maybe Hanny is down by the canal,” Vevi suggested. “Or in the cheese house,” added Connie. The two girls enjoyed showing Rosemary, Jane and Sunny over the farm. Because they wanted to keep the secret to themselves, they did not tell the others about the locked door or the mystery connected with it. In passing the little building, though, they noticed that the padlock still was clamped shut. “Where can Hanny be?” Jane speculated. “Maybe she is out in the fields,” Sunny suggested.
