THE WORLD'S ADVANCE

a moment and sped out from under 

 the very bow of the battleship. He took 

 the picture as the big ship was making 

 the last of her twenty-one trial runs and 

 was under forced draft, going at a speed 

 of twenty-three knots an hour. 



The snapshot of the battleship was 

 made "bow on" and is probably the best 

 picture of its kind ever taken. 



THRESHING FOREST SEED WITH 

 A SIMPLE DEVICE 



Every spring for the past few years 

 the Forest Service has been setting out 

 hundreds of thousands of young pine 

 trees on the barren ranges of the west- 

 ern mountains. These young plants are 

 first grown from seed in immense nurs- 

 eries in which the seed is planted and 

 grown just as in a private garden. 



The hundreds of bushels of seed are 

 bought from the farmers and settlers. 

 The seeds are dried and then placed in 

 a big, wire-meshed hopper and threshed 

 out quickly. The threshing device, which 

 is shown in the illustration below, is a 

 simple device which is turned by hand. 

 The seeds drop into a bin below, while 

 the cones remain in the screened box. 



It is estimated that at least ten million 

 young trees have been set out in the West 

 this year. While these are mostly pine, 

 there are also large quantities of larch, 

 spruce, fir and cedar, but all that are 

 thus grown are of the cone-bearing 

 family of trees.

Thin Slabs of Concrete Placed Over the Brick Walls 



of this Church have Given it the Appearance of a 



New Building. 



IMITATION STONE MADE FROM 

 CONCRETE 



Frame or brick houses can be faced 

 with thin blocks of concrete so that a 

 close imitation to stone results. The 

 blocks are made in various sizes with 

 a number of molds. A brick church 

 which has been clad in a new dress to 

 closely imitate colored sandstone is shown 



in the accompanying illustration. 



The change was made in about 



three weeks. 



At last the question of how 

 England can transport her 

 troops across the Channel to 

 Fiance, in the face of the Ger- 

 man submarine blockade, is ex- 

 plained. It is said that a netting 

 extends across the Channel, thus 

 preventing attacks on troop 

 ships. The netting is made of 

 heavy cables that are woven into 

 meshes 18 inches square, thus 

 making an effective barrier 

 against submarines and tor- 

 pedoes.
