PRELIMINARY MEETINGS. 903 
make shipments between June 1 and August 1, arrangements must be made by 
them for special inspections during this period. 
“The following was adopted as the general form of the certificate: 
“This is to certify that the nursery premises and growing stock of ; 
situated in , have been inspected according to the provisions of the law 
[here insert title of act under which inspections are made], and no indications 
have been found of the presence of the San Jose scale or other dangerous |or 
dangerously injurious] insects or plant disease. This certificate is invalid after 
June 1, 189—. 
“Date, 
‘Hach inspector should prepare a list of official inspectors of other States 
and Territories whose certificates will be accepted by him as valid, and this 
list should be sent by each inspector to all nurserymen within his own State 
whose premises have been inspected and certified, with information that they 
will be at liberty to attach the certificate of their own State inspector to all 
nursery stock received by them bearing the official certificate of any one of the 
‘inspectors on the above-mentioned list. This arrangement is supposed to relieve 
nurserymen from the impracticable requirement of sending with each lot of 
stock disposed of a copy of each original certificate which this stock may have 
borne. These lists of accredited inspectors may also be furnished to dealers 
in nursery stock who do not themselves own nursery premises, provided the 
State inspector is satisfied of their honesty and responsibility. } 
“The presence of the San Jose scale, of peach yellows, of rosette, and of the 
black-knot of the plum should be regarded in all cases as ground for withhold- 
ing a certificate until premises have been completely freed from them. 'The 
presence of the woolly aphis, of the oyster-shell scale, of the scurfy scale, of 
anthracnose, and of other common and wide-spread injurious insects and diseases 
should not be regarded as a bar to a certificate unless they are exceptionally 
abundant, so as to affect the value of the stock and to render likely an unusual 
increase or more general introduction of these insects and diseases, provided 
such infested or infected nursery stock is sold and shipped. 
“Inspections should include not only the nursery stock to be certified, but also 
stock left over from previous years, old trees, and the like, together with sur- 
rounding premises in general.” 
In response to numerous requests, steps were taken December 1, 1900, toward 
still another conference, in consequence especially of difficulties and inconsis- 
tencies in administration which had appeared, some of them threatening trouble 
between the responsible officers in different States. “ For example, the law in 
one State requires that all inspections shall be finished not later than August 15, 
and the official inspector in another State has given general notice that any cer- 
tificate dated earlier than August 15 will be disregarded in his State.” 
This call was made to include representatives of Kansas, Colorado, Tennes- 
see, Wisconsin, Pennsylvania, New York, Nebraska, Michigan, Kentucky, and 
Iowa, and the meeting was held in Chicago January 4, 1901. The proceedings 
of this meeting were reported by circular letter distributed January 14, and 
were as follows: 
“At a conference of horticultural inspectors of the States of New York, 
Michigan, Indiana, Illinois, Iowa, Kentucky, and Tennessee held at the Palmer 
House, Chicago, January 4, 1901, the general subject of the methods and ob- 
jects of nursery inspection was broadly discussed, with special attention to cer- 
tain details in which a comparison of views was thought to be particularly 
desirable.
