510 ANNUAL EEPOETS OF DEPARTMENT OF AGRICULTURE. 



The old Trinity Bay district has been declared a regulated zone 

 by orders of March 15 and April 24. This zone includes all of the 

 counties surrounding Trinity Bay included in the noncotton zone of 

 1918, except the extreme western portion, which has been released 

 from all quarantine restrictions. This is the important cotton-pro- 

 ducing territory bordering the Brazos River in Brazoria and Fort 

 Bend Counties, which Avas included in the quarantine of 1918 merely 

 as an additional safeguard. 



The territory actually infested in 1917 in the small Hearne dis- 

 trict has been continued as a noncotton zone by an order dated April 

 24. Furthermore, cotton grown within a radius of 3 miles of such 

 zone is brought under regulation by another order of the governor 

 of the same date. 



By orders dated April 9, 1919, the governor of Texas has reissued 

 under the new act the old border noncotton zone, including Maverick, 

 Kinney, and Valverde Counties, and has established additional quar- 

 antine zones to cover the new infested territory in western Texas. 

 These are a noncotton zone comprising the counties of Presidio and 

 Brewster, which include the infested territory in the Great Bend 

 of the Eio Grande, and a special zone comprising the counties of 

 Ward and Eeeves to include the infested territory of the Brazos 

 River. Supplementing the latter special zone, two proclamations 

 A\ ere issued b}- the governor of Texas under date of IMay 1, 1919, es- 

 tablishing regulated zones covering all territory within 5 miles of 

 and including the fields in Ward and Reeves Counties which were 

 determined as infested with the pink bollworm as to the crop of 

 1918. 



After a conference with the Federal authorities cooperating with 

 tlie State of Texas in the pink bollworm work, regulations were issued 

 under date of April 24, 1919, by the commissioner of agriculture of 

 Texas, governing the planting and the safeguarding of the cotton 

 crop produced in the three regulated zones. In other w^ords, cotton 

 may now be grown u.nder regulation in all the zones established in 

 the interior of Texas, with the exception of a small portion of the 

 Hearno zone, and the growth of cotton is prohibited in two border 

 zones involving the Great Bend district and the old border noncotton 

 zone of last year, including the counties of ISIaverick, Kinney, and 

 Vah'crde. 



THE PINK BOLLWORM IN BIEXICO. 



The survey and inspection of the cotton grown near the border of 

 Mexico adjacent to the United States has been continued, covering- 

 the more important areas betAveen BroAvnsvillc and P^agle Pass, Tex. 

 No ncAV infestation lias actually been found anyAvhere near the bor- 

 der in this portion of Mexico. One locality, hoAvever, at Guerrero, 9 

 miles from the Texas border, opposite the town of Zapata, is under 

 suspicion because of the determination that certain fields at that 

 place Avere planted from seed obtained from an infested locality in 

 Mexico. This planting has a special importance from the fact that a 

 stream of considerable size floAving from this district discharges into 

 the Eio Grande not far above extensive cotton cultures in both Mex- 

 ico and the United States, and therefore may ultimately be the means 

 of conveying the insect to tliese cultures.
