THE GARMENTS. 



The underwear and the hat linings designated for the experiment 

 arrived in Manila about the first- of December, 1908, and were distributed 

 to the posts shortly thereafter. Difficulties began to be encountered 

 upon the arrival of the requisitions. An undue proportion of small 

 sizes of the garments was found to be present, this being particularly 

 true of the orange-red undershirts. Onl}- about 1,100 of the 5,000 sent 

 were of sizes 36 and 38, which are worn by a majority of men. Therefore, 

 rather more of a selection of men was necessary than at first was con- 

 templated or thought desirable, a larger proportion of smaller men 

 being required for the experiment. 



The estimate of the War Department officials for five suits of under- 

 wear per man for the year, brought forth protests from a number of 

 post and organization commanders, the calculations of the latter running 

 from about eight to fifteen suits per man. As the purpose of the 

 experiment would be defeated if an insufficient supply of the garments 

 were furnished, it was decided that the needs of the wearers must be 

 met. For the above reasons, the number of men actually equipped and 

 kept under observation fell short of the original estimates. About 500 

 men in all were equipped with special underwear, including 20 men of 

 the Hospital Corps at the Division Hospital, Manila, and 40 general 

 prisoners at the Port William McKinley prison. An equal number of 

 controls with white underwear were used. 



The undershirts issued were those that have been provided for some 

 years past under the name of "undershirts, cotton/' a garment with a 

 round neck, without buttons, and weighing approximately 8.5 ounces. 

 The drawers were different from anything that recently has been issued, 

 being a rather superior garment of heavy jean with webbing inserts at 

 the seams. The weight of this garment was 8.9 ounces. 



The colored garments when received were of a deep, orange-red color, 

 the red predominating. The dyeing of the garments was very nearly
