WALKS. 



In the majority of large plants visited, no permanent paths or walks were to 

 be found. In all houses having raised benches a path would be found in between 

 beds. The growers at the present time seem to be eliminating everything that 

 hinders the most intensive cultivation of the soil under glass. Where all crops are 

 grown on the soil, and where horses are used to prepare the soil for the crop, no 

 paths are to be found, because they would be more of a hindrance than a help. 

 Sufficient room is left at intervals in planting the crop to allow for passage between. 

 In the majority of cases the ordinary greenhouse soil is trodden down until it 

 becomes solid for walking. In some oases men lay a ten or twelve inch board 

 down the house and use this for a walk. Never a slat walk 18 inches or two feet, 

 this would be a waste of productive soil. In other houses concrete walks are to be 

 found. These are usually about 12-15 inches wide, and are made on either side of 



Walks are usually 12 to 15 In. wide, allowing ample room for crop to grow.

 room possible for the growing of the crop. 



More elaborate houses have a concrete walk with a 3-5 inch side, which acts as 

 a side for the bed, being 3-1 inches high. These walks are never more than 18 

 inches in width. Where a house is fitted out in this manner there is usually some 

 good reason for it, which usually amounts to the grower having easy access to a sand 

 or gravel pit or that the paths are a necessity to accommodate the visitors. In 

 making concrete walks the foundation should be down about 5-6 inches. Coarse 

 stones and gravel will do for this, and should be made at the ratio of 6-1 with
