 To the Rose our gardens owe much of their beauty, while our summer hedges 

 are rendered sweet and attractive by the wild Dog-roses, of red or white hue, 

 which are scattered among the leafy boughs. Rose-water, attar of roses, and 

 conserve of roses, are yielded by preparations of the petals and the hips.
