took a renewal of the lease of the mill site and garden, 

 retaining the plot of ground on the north of the mill 

 race, which they held jointly with the mill site. The 

 wall of the premises was thrown down, and rebuilt 

 on range with the Society's wall ; by which the road 

 was widened eight or nine feet. The mill and house 

 being in a ruinous state, the latter was removed, but 

 the mill was repaired, as it was thought it might be 

 useful for trials and experiments in dressing hemp and 

 making cement for masonry. In any case, it was felt 

 that the Society must necessarily have full command 

 over the river Tolka, which bounds the Garden on the 

 north. Later on, dangerous accidents were said to have 

 occurred from insecure and improper passages to the 

 islands in the river Tolka, and the matter was re- 

 ferred to a committee. In 1817, special attention was 

 directed to the ruinous and disgraceful state of the 

 mill at Glasnevin, which cost the Society in purchase, 

 fines, and rent, 1184, nj. lid. A flush weir was 

 made at an expense of 13, and the mill and two 

 acres adjoining were let to Mr. John Hill, of 

 Eden quay, at 70 a year, he to expend 500. 

 This tenant was afterwards proceeded against for wilful 

 waste and non-payment of rent. Breaches were made 

 in the wall, and in May 1823, a great flood caused 

 breaches in the garden bank and weir. Obstructing 

 matter had afterwards to be removed from the bed of 

 the river when the water was low, and a wall to protect 

 the bank was erected. In 1805, the gates of the 

 Glasnevin turnpike were removed to the bridge over 

 the river, as their then position was a hindrance to 

 many attending the Garden. 



The Rev. Thomas Hincks, in 1810, presented a 

 Flora of the county Cork, and sent up rare plants for 

 the hothouse. Soon after, an experiment was tried in
