YOU SAID:
The mountains sides were green with woods and all the sheltered valleys rich and pleasant
INTO JAPANESE
山の側面は森と豊かで快適なすべての保護された谷に緑だった
BACK INTO ENGLISH
The side of the mountain forests and rich and comfortable all the protected Valley was green
INTO JAPANESE
すべての保護された谷は緑山の森林の側面と豊かで快適です
BACK INTO ENGLISH
All the protected Valley sides of green mountain forest and lush and comfortable
That didn't even make that much sense in English.
