522 ANNUAL PvEPOETS OF DEPARTMENT OF AGRICULTURE. 



;i greater efficiency, after a stated public hearing, February 24:, 1919, 

 a quarantine was issued April 15, 1919, effective May 1, 1919. This 

 quarantine points out that the susceptible varieties of barberry and 

 the related Mahonias have been very largely eradicated from the 

 States of Nebraska, Iowa, Illinois, Indiana, Ohio, Xorth Dakota, 

 South Dakota, Minnesota, Montana, Wisconsin, Michigan, Wyoming, 

 and Colorado and therefore quarantines all the other States of tlio 

 United States, including the District of Columbia, and orders that 

 no plants of the species of Berberis and Mahonia enumerated in the 

 quarantine shall be moved or allowed to move to points outside of 

 the quarantined areas. 



This quarantine places no restriction on the movement of the 

 Japanese barberry and the Japanese Mahonia, the most valuable 

 and most commonly planted of the barberries and JNlahonias, and 

 which are not alternate hosts of the disease. 



COTTON IMPORTATIONS. 



The restrictions placed on the entr}- of foreign raw cotton, cotton 

 waste, cotton wrappings, and cotton seed and cottonseed products, to 

 prevent the entry of the pink boll worm and other dangerous cotton 

 pests, are being continued. 



The entry of foreign cottons and of such cotton waste and cotton 

 wrappings as must be fumigated as a condition of entry is limited to 

 the ports of Boston, New York, San Francisco, and Seattle, where 

 fumigating plants for this purpose have been provided. The entry 

 of cotton waste and cotton wrappings for which disinfection is not 

 required is permitted at any port where the board maintains inspec- 

 tion service. 



The importation of foreign cotton Avas considerably reduced dur- 

 ing the year as a result of war conditions, amounting to a total 

 of only 179,537 bales. Tlic cotton indicated in the tables given below 

 as from the United States represents returned American cotton, and 

 that indicated from Calexico, Mexico, is cotton permitted entry from 

 the Imperial Valley, Lower California. These two items were en- 

 tered without requirement of disinfection or other restrictions. 



The entry of cotton waste comes in two classes, restricted and un- 

 restricted, the former requiring disinfection and subsequent control 

 as to utilization the same as foreign cottons. Manufactured waste 

 from which all c otton seeds have been removed and v>-aste from Amer- 

 ican cotton may be entered under permit without the requirement of 

 disinfection or other restrictions. Some 115 bales of waste were 

 entered after disinfection. Some 15,000 bales were entered without 

 disinfection. The latter represents very largely American cotton 

 waste which was purchased for utilization in Canada for war pur- 

 poses and resold and returned to the United States at the close of 

 hostilities. 



The restrictions on the entry of cotton wrappings or bagging aro 

 necessitated by the fact that such wrappings carry considerable quan- 

 tities of cotton and rotton seed, and tho)-eforo must l)e subjected to rc- 

 st]'i'--tions similar (o those a])plying to the enli'v of cotton. Duringtho 

 year 24,23G bales of bagging entered the United States. Of this 

 amount 2,277 bales were fumigated and the balance were permitted
