522 ANNUAL REPORTS OF DEPARTMENT OF AGRICULTURE. 



ji greater efficiency, after a stated public hearing, February 24, 1919, 

 11 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, North Dakota, 

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

 and Colorado and therefore quarantines all the other States of tlie 

 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 tlie 

 Japanese barberry and the Japanese Mahonia, the most valuable 

 and most commonly planted of the barberries and Mahonias, and 

 which are not alternate hosts of the disease. 



COTTON IMPORTATIONS. 



The restrictions iDlaced on the entry of foreign raw cotton, cotton 

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

 prevent the entry of the pink bollworm 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 

 fmnigating 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 was considerably reduced dur- 

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

 of only 179,537 bales. The 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 entr}^ 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, I'cstricted and un- 

 restricted, the former requiring disinfection and subsequent control 

 as to utilization the same as foreign cottons. Manufactured waste 

 from which all cotton seeds have been removed and waste from Amer- 

 ican cotton may be entered under permit without the requirement of 

 disinfection or other restrictions. Some 415 bales of waste wore 

 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 cotton seed, and therefore must be subjected to re- 

 strictions similar to those applying to the entry of cotton. During the 

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

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