The plant kingdom covers the entire earth, offering our senses great pleasure and the delights of summer.

When all the thoughts are concerning one thing and the person loses interest in other things, the melancholy begins.

Nature does not proceed by leaps.

No one has been a greater botanist or zoologist. No one has written more books, more correctly, more methodically, from personal experience. No one has more completely changed a whole science and started a new epoch.

As one sits here in summertime and listens to the cuckoo and all the other bird songs, the crackling and buzzing of insects, as one gazes at the shining colors of flowers, doth one become dumbstruck before the Kingdom of the Creator.

The plant kingdom covers the entire earth, offering our senses great pleasure and the delights of summer.

If a tree dies, plant another in its place.
