She consented, and Rollo, when he came back through the kitchen, said to Dorothy, who was sitting at the window, sewing, "Dorothy, we are going to get some blue-bells to press." "Ah!" said Dorothy. "Where are you going for them?" "O, out by the bridge," said Rollo, as he passed on to go out at the door. "O Rollo!" said she, calling out to him suddenly, as if she recollected something; "stop a minute." So Rollo came back to hear what she had to say. "You are going pretty near the village." "Yes," said Rollo. "And could you be so kind as to do an errand for me?" "Yes," said Rollo; "what is it?" Then Dorothy went to her work-table, and began to open it, saying all the time, "I want you to get some medicine for Sarah, for she is sick." Sarah was a friend of Dorothy's, who lived at another house, not far from Rollo's; and Rollo used sometimes to see her at his father's, when she came over to see Dorothy. She was in very feeble health, and now wanted some medicines. Dorothy had been over at the house where she lived that day, and had found that the doctor had left her a prescription; but she had nobody to send for it, and she was not quite able to go herself. So Dorothy told her that if she would let her have the money, she would ask Rollo or Jonas to go. So Sarah gave her a dollar bill, and in order to keep it safe, she put it in a little morocco wallet, and tied it up securely with a string. This wallet was what Dorothy was looking for, in her work-table. She took it out, and untied the string. She opened the wallet, and showed Rollo the money in one of the pockets, and a small piece of white paper, upon which was written the names of the medicines which the doctor wished Sarah to take. Such a writing is called a _prescription_. Rollo looked at the prescription to see what sort of medicines it was that he was to get, but he could not read it. The words were short and strange, and had periods at the end of them,--which Rollo told Dorothy was wrong, as periods ought to be only at the end of a sentence. Then there were strange characters and marks at the ends of the lines; and Rollo, after examining it attentively, said he could not read a word of it, and he did not believe that the apothecary could. However, he said he was willing to take it to him, and let him try. He accordingly put the prescription back again carefully into the wallet, and Dorothy tied it up. Then he put it into his pocket, and went out to James. He found James waiting by the gate, and they both walked along together.
