Page 5 - It was on the day, or rather night, of the 27th of June 1787, between the hours of eleven and twelve, that I wrote the last lines of the last page in a summer-house in my garden. After laying down my pen, I took several turns in a berccau, or covered walk of acacias, which commands a prospect of the country, the lake, and the mountains.
Page 321 - Let's dry our eyes : and thus far hear me, Cromwell ; And — when I am forgotten, as I shall be, And sleep in dull cold marble, where no mention Of me more must be heard of — say, I taught thee, Say, Wolsey — that once trod the ways of glory, And sounded all the depths and shoals of honor...
Page xxxviii - Their downy breast; the swan with arched neck, Between her white wings, mantling proudly, rows Her state with oary feet...
Page 99 - From you have I been absent in the spring, When proud-pied April dress'd in all his. trim Hath put a spirit of youth in every thing, That heavy Saturn laugh'd and leap'd with him. Yet nor the lays of birds nor the sweet smell Of different flowers in odour and in hue Could make me any summer's story tell, Or from their proud lap pluck them where they grew...

Page 6 - I cannot name this gentleman without remarking that his labours and writings have done much to open the eyes and hearts of mankind. He has visited all Europe,— not to survey the sumptuousness of palaces, or the stateliness of temples; not to make accurate measurements of the remains of ancient grandeur, nor to form a scale of the...
Page 163 - How sleep the brave who sink to rest, By all their country's wishes blest ! When Spring, with dewy fingers cold, Returns to deck their hallowed mould, She there shall dress a sweeter sod Than Fancy's feet have ever trod. By fairy hands their knell is rung ; By forms unseen their dirge is sung ; There Honour comes, a pilgrim gray, To bless the turf that wraps their clay ; And freedom shall awhile repair, To dwell a weeping hermit there ! ODE TO MERCY.
Page 305 - See! from the brake the whirring pheasant springs, And mounts exulting on triumphant wings: Short is his joy; he feels the fiery wound, Flutters in blood, and panting beats the ground. Ah! what avail his glossy, varying dyes, His purple crest, and scarlet-circled eyes, The vivid green his shining plumes unfold, His painted wings, and breast that flames with gold?
Page 322 - Love thyself last: cherish those hearts that hate thee ; Corruption wins not more than honesty. Still in thy right hand carry gentle peace, To silence envious tongues. Be just, and fear not: Let all the ends thou aim'st at be thy country's, Thy God's, and truth's...
Page 312 - O'er all the Italian fields, where still doth sway The triple Tyrant ; that from these may grow A hundredfold, who, having learnt thy way, Early may fly the Babylonian woe.
