skill, and diligence, in his vacation-times (by no means extensive), which deserves much 
credit and encouragement.

This letter was accompanied with the following “ Statement ” by Mr. George Clark, 
Master of the Government School at Mahebourg, Island of Mauritius : — 
“ On the estate called ‘ Plaisance,’ abont three miles from Mahebourg, in the island 
of Mauritius, there is a ravine of no great depth or steepness, which, apparently, once 
conveyed to the sea the drainings of a considerable extent of circumjacent land, but 
which has been stopped to seaward, most likely for ages, by an accumulation of sand 
extending all along the shore. The outlet from this ravine having been thus impeded, 
a sort of bog has been formed, called ‘ La Mare aux Songes,’ in which is a deposit of 
alluvium, varying in depth, on account of the inequalities of the bottom, which is formed 
of large masses of basalt, from three to ten or twelve feet. The proprietor of the 
estate a few weeks ago conceived the idea of employing this alluvium as manure ; and 
shortly after, the men began digging in it ; when they had got to a depth of three or 
four feet they found numerous bones of large tortoises, among which were a carapace 
and a plastron pretty nearly entire, as also several crania. 
“ When I heard of this, it immediately struck me that the spot was one of the most 
likely possible to contain bones of the Dodo, and I gave directions to the men working 
there to look out for any bones they might find. Nothing, however, was turned up but 
a fragment of what I supposed to be the humerus of a large bird. This encouraged 
me to look further ; and my search was rewarded by the discovery of several tibiae, more 
or less perfect, two tarsi, one nearly perfect pelvis, and fragments of three others. 
“ These were found imbedded in a black vegetable mould, the lighter-coloured 
specimens being near the springs. My reasons for believing these to be remains of the 
Dodo are ; — the certainty that that bird once existed in Mauritius ; the similarity of 
these bones to what the representations of the Dodo which I have seen would lead one 
to expect, particularly the breadth of the pelvis, the stoutness of the tibiae and tarsi, 
and the shortness of the latter ; the favourable nature of the spot in which they were 
found for the haunts of such birds when living — a sheltered hollow with two springs 
in it ; the non-existence, actual or traditional, in Mauritius of any bird to which bones 
such as these could have belonged ; the indubitable antiquity of these bones, proved by 
the deposit of alluvium which covered them.
