LAW OF UNIVERSAL GRAVITATION

I was reading a book under the plum tree yesterday.  I heard a little sound of something fallen on the ground.

I looked for something, and found a ripe plum.

A duck was watching a phenomenon of law of universal gravitation.  

A purple ripe plum.   It tasted much sour. 

This is another variety of plum, 'Santa Rosa'.  It's fruits ripen two to three weeks later than 'Oishi Wase', and they are suitable for making jam.

We will make plum jam, next week.
