AMERICAN HOMES AND GARDENS 



Vll 



THE FLOATING FARMS OF CHINA 



ACCORDING to an exchange, like the 

 wood merchants of northern Russia, 

 u1k> carry their wood on great rafts, 

 to Nijni-Novgorod, Kazan, and Astra- 

 kan, tJie tanners of the upper and cen- 

 tral regions along the 1 ang-ste-Kiang 

 construct rafts covering as much as two 

 acres of surface, and on the rafts they 

 establish farms where produce grows. On 

 these great floating farms are habitations 

 for the men and stables for the animals, 

 pig-pens, feed-barns, and storehouses well 

 stocked with provisions. The voyage to 

 market is often one thousand miles, and 

 to employ their time on the slow journey 

 the dwellers on the rafts make baskets 

 and many objects of household use. Ar- 

 rived at their destination, they sell their 

 produce, take apart and sell the rafts, and 

 return to their homes by the ways used 

 by ordinary travelers. 



COLORED MOVING PICTURES 



THE popularity of moving pictures has 

 stimulated investigations in color pho- 

 tography. It was agreed, says a writer in 

 Harper's Weekly, that the public would 

 never be satisfied until scenery and action is 

 depicted in all the colors of life. To supply 

 this demand many films were colored by 

 hand. This method was not only laborious, 

 but was not true to life. 



While color photography was being 

 studied, there was suddenly put on ex- 

 hibition a process that is as remarkable as 

 the moving picture itself, its effectiveness 

 being based on the same principle. 



In the moving picture, a succession of 

 views, taken at the briefest intervals, and 

 flashed upon a screen, is presented to the 

 eye as more or less gradual motion, accord- 

 ing to the number of projections per 

 second. The same idea is used in the color 

 display. In its simplest performance, the 

 process is as follows : The spectrum — 

 with range of colors from white through 

 yellow, orange, red, green, blue, violet, and 

 indigo to black — is separated into two 

 divisions; orange-red and green-blue. 

 What the spectator would see, if the film 

 were moved slowly, would be first an 

 orange-red picture and then a green-blue 

 one. When the film moves rapidly, the 

 illusion is a scene in all the colors of the 

 spectrum, as produced by orange-red and 

 green-blue and their combinations. This 

 is because of what is known as the per- 

 sistence of vision, an optical phenomenon 

 that is thus played upon to produce the 

 illusion of color as well as motion. 



However, the film itself is not colored. 

 It looks like the ordinary film consisting 

 of blacks, whites and grays. It is not pro- 

 duced in the usual way, however. In 

 taking the pictures, gelatine color-filters 

 are moved before the film simultaneously 

 with the instantaneous exposures. One 

 snapshot is taken through the red filter, 

 and the next through the green. 



The negatives Cor the positives, as they 

 must be for exhibition purposes) contain 

 the scene with the color values filtered 

 alternately through red and green. When 

 the pictures are projected on the exhibi- 

 tion screen, another disk of colored gela- 

 tine rotates before the film simultaneously 

 with each picture. The color values in 

 blacks, whites and grays that the filter 

 originally allowed to pass to the film are 

 now flashed back from the film, through 

 the rotating colored disc. The result is 

 a portrayal of motion and color, with some 

 unnatural effects, it must be admitted, as 

 to brilliancy of hue, yet splendid and thor- 

 oughly pleasing.

Since 1847 



The firm of Peter Henderson & Co. was founded in 1847 and the 66 

 years of successful seed-raising and selling that is behind every package 

 of Henderson's seeds must and does make them the best that it is possi- 

 ble to buy. In your grandfather's day, Henderson's was the standard by 

 which other seeds were judged and the same condition exists in 1913. 

 Our methods of seed-testing which were the best three generations ago 

 have been improved upon from year to year and are to-day still the best. 

 The unknown quantity in your garden is the quality of the seeds 

 you plant and you cannot be too careful in seeing that you obtain the 

 best procurable. The most critical of all planters in the choice of their 

 seeds are the market-gardeners or truck-farmers. Perhaps the best en- 

 dorsement of the quality of Henderson's seeds is the fact that Peter 

 Henderson & Co. supply a larger number of professional growers than 

 any two-seed houses in the world. The very existence of 

 these men depends upon their receiving the best quality 

 of seeds. That Peter Henderson & Co. are easily preemi- 

 nent in the professional growing field is the best endorse- 

 ment of Henderson's seeds that can be given. 

 Henderson's seeds are tested seeds.
