Решение:

1) Jim was going to have a hard struggle for his happiness;
Jim knew that Rosy's father, Mr. Riddle, would not approve of their relationship, so he anticipated a difficult time convincing him.

2) Mr. Riddle didn't allow his daughter to marry Jim;
Mr. Riddle was likely against Jim for some reason, possibly due to social status, financial standing, or his perception of Jim's character.

3) Jim wanted to give Rosy a love-drug;
Jim believed that if Rosy took a love-drug, she would fall in love with him, overcoming any resistance from her father or her own potential doubts.

4) Jim applied to Pilkins for a love-drug;
Jim needed someone to procure the love-drug for him, and Pilkins was the person he turned to, likely because Pilkins had access to such substances or knew how to obtain them.

5) Pilkins handed Jim a sleeping-pill instead of a love-drug;
Pilkins, perhaps out of malice, a sense of morality, or a misunderstanding, gave Jim a sleeping pill instead of the requested love-drug. This action directly led to the tragic outcome.

6) all night Pilkins waited for the news of the tragedy;
Pilkins was likely anticipating a negative outcome, possibly feeling guilty or anxious about the consequences of his actions or inaction.

7) Jim had a victorious smile on his face;
Jim was under the impression that the love-drug had worked, and he was pleased with the perceived success of his plan, unaware of the tragic reality.
