PRELIMINARY MEETINGS. 203 



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, . 



" Each 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.
