sufficient. The total exclusion of all vines should be maintained ; the 
admission of all other plants from countries where Phylloxera in the 
vine does not exist should be allowed; and the admission of plants 
satifaetory certification that they have not been grown in the — 
vicinity of vines. 
It can hardly be doubted that had it been iun from the first to 
enforce such regulations efficiently, South Africa would have remained 
free from the ravages of the Phylloxera. Noverthelées, it appears from 
the evidence of Mr. Louis Peringuey before the Select Committee of 
the Cape House of Assembly on the Vineyards Diseases Act (presented 
with their report, July 29 of the present year) that the insect was first 
identified by him in South Africa on January 1, 1886. “It came from 
Kotze's at Mowbray.” [Qs. 936 and 937.] This is in the neighbour-

Havsa been ec by es French Government, in accord- 
ance with your request, to come and inspect the vineyards of the Cape 
Colony, as regards their protection from the Phylloxera, E entered upon 
this duty immediately after my arrival. In company with Professor 
chen the Secretary for Agric, and M. Peringuey, Inspector of 
neyards, I visited the principal wine-farming centres, and now have 
the. honour of submitting to you the observations i have made, and the 
‘conclusions to be drawn therefrom 
* Although the existence of the Phylloxera in the vineyards of the 
Colony was not verified officially before the year 1886, the disease is, 
in my opinion, of much earlier date, and in accordance with Mons. 
Peringuey, wh o has made a special study of the question, I consider that 
the invasion of "this destructive insect should be approximately fixed at 
about the year 1880. 
*T shall say nothing respecting its introduction into the Colony, 
That seems to be a question which will never be definitely decided. On 
the other hand, I had no difficulty in S eei rving that me Phylloxera, as 
was to be expected, had run E d begs course here as in Europe, a 
its peculiarities have been the e end that its effect upon the vin 
has been amend all these da 1 ‘eine well understood. But there fs is 
this very import ant difference, s a owing to the mildness of the climate 
of the Cape, dere is, all the year through, no check to its reproductive 
powers, and consequently its increase is far more rapid than in Europe. 
Tt has also been ascertained that the production of winged females, 
whose special function is the wide dispersion of the species, lasts for a 
much longer time here than in the northern oy ing ee pet is to if
